Overview The​ ​Mutamix​ ​is​ ​a​ ​mixer​ ​that​ ​has​ ​been​ ​mutated​ ​to​ ​offer​ ​unique​ ​and​ ​powerful functionality.​ ​Up​ ​to​ ​six​ ​channels​ ​of​ ​audio​ ​or​ ​CV​ ​signals​ ​can​ ​be​ ​mixed​ ​and​ ​routed​ ​to​ ​the three​ ​selectable​ ​Bus​ ​outputs.​ ​Channels​ ​can​ ​be​ ​muted​ ​or​ ​soloed​ ​using​ ​buttons,​ ​but​ ​also muted​ ​using​ ​trigger​ ​or​ ​gate​ ​signals.​ ​Muting​ ​arrangements​ ​can​ ​be​ ​saved​ ​as​ ​presets​ ​for quick​ ​recall,​ ​and​ ​in​ ​X-Mode​ ​these​ ​presets​ ​can​ ​be​ ​step​ ​sequenced​ ​and​ ​randomized​ ​to inject​ ​life​ ​into​ ​your​ ​patches. Jumpers​ ​on​ ​the​ ​back​ ​allow​ ​the​ ​Mutamix​ ​faders​ ​to​ ​send​ ​a​ ​five​ ​volt​ ​range​ ​while​ ​an​ ​input​ ​is not​ ​connected,​ ​creating​ ​step​ ​sequencing​ ​functionality​ ​while​ ​in​ ​X-Mode.​ ​A​ ​Linix​ ​module can​ ​also​ ​be​ ​connected​ ​using​ ​a​ ​ribbon​ ​cable​ ​to​ ​normal​ ​the​ ​two​ ​together. This​ ​flexible​ ​configuration​ ​means​ ​that​ ​the​ ​Mutamix​ ​can​ ​function​ ​as​ ​an​ ​audio​ ​and​ ​CV mixer,​ ​sequential​ ​switcher,​ ​voice​ ​allocator,​ ​step​ ​sequencer,​ ​and​ ​complex​ ​modulation distributor. Features ● Six​ ​channel​ ​CV/audio​ ​mixer​ ​with​ ​LED​ ​faders​ ​to​ ​set​ ​input​ ​levels,​ ​mute/solo​ ​buttons,​ ​and three​ ​selectable​ ​Bus​ ​Outputs. ● Preset​ ​saving​ ​and​ ​loading​ ​of​ ​mute​ ​arrangements. ● X-Mode​ ​allows​ ​quick​ ​recall,​ ​as​ ​well​ ​as​ ​step​ ​sequencing,​ ​inversion,​ ​and​ ​randomization​ ​of muting​ ​arrangements. ● +5V​ ​jumper​ ​allows​ ​the​ ​sliders​ ​to​ ​send​ ​a​ ​five​ ​volt​ ​range​ ​without​ ​an​ ​input​ ​connected, allowing​ ​the​ ​Mutamix​ ​to​ ​function​ ​as​ ​a​ ​step​ ​sequencer. ● Attenuation​ ​on​ ​Bus​ ​Outputs​ ​A​ ​and​ ​C. ● Jumpers​ ​to​ ​normal​ ​Linix​ ​output​ ​to​ ​the​ ​six​ ​inputs. ● Skiff​ ​friendly​ ​38mm​ ​depth. ● Firmware​ ​updateable​ ​via​ ​Intellijel​ ​USB​ ​ISP​ ​or​ ​other​ ​AVR​ ​programmer.

Installation Intellijel​ ​Eurorack​ ​modules​ ​are​ ​designed​ ​to​ ​be​ ​used​ ​with​ ​a​ ​Eurorack-compatible​ ​case​ ​and​ ​power supply. Before​ ​Your​ ​Start Before​ ​installing​ ​a​ ​new​ ​module​ ​in​ ​your​ ​case​ ​you​ ​must​ ​ensure​ ​your​ ​case’s​ ​power​ ​supply​ ​has sufficient​ ​available​ ​capacity​ ​to​ ​power​ ​the​ ​module: ● Sum​ ​up​ ​the​ ​specified​ ​+12V​ ​current​ ​draw​ ​for​ ​all​ ​modules,​ ​including​ ​the​ ​new​ ​one.​ ​Do​ ​the same​ ​for​ ​the​ ​-12​ ​V​ ​and​ ​+5V​ ​current​ ​draw.​ ​The​ ​current​ ​draw​ ​will​ ​be​ ​specified​ ​in​ ​the manufacturer's​ ​technical​ ​specifications​ ​for​ ​each​ ​module. ● Compare​ ​each​ ​of​ ​the​ ​sums​ ​to​ ​specifications​ ​for​ ​your​ ​case’s​ ​power​ ​supply. ● Only​ ​proceed​ ​with​ ​installation​ ​if​ ​none​ ​of​ ​the​ ​values​ ​exceed​ ​the​ ​power​ ​supply’s specifications.​ ​Otherwise​ ​you​ ​must​ ​remove​ ​modules​ ​to​ ​free​ ​up​ ​capacity​ ​or​ ​upgrade​ ​your power​ ​supply. You​ ​will​ ​also​ ​need​ ​to​ ​ensure​ ​you​ ​have​ ​enough​ ​free​ ​space​ ​(hp)​ ​ ​as​ ​well​ ​as​ ​free​ ​power​ ​headers​ ​in your​ ​case​ ​to​ ​fit​ ​the​ ​new​ ​module. You​ ​can​ ​use​ ​a​ ​tool​ ​like​ ​ModularGrid​ ​to​ ​assist​ ​in​ ​your​ ​planning.​ ​Failure​ ​to​ ​adequately​ ​power​ ​your modules​ ​may​ ​result​ ​in​ ​damage​ ​to​ ​your​ ​modules​ ​or​ ​power​ ​supply.​ ​If​ ​you​ ​are​ ​unsure,​ ​please contact​ ​us​ ​before​ ​proceeding. Installing​ ​Your​ ​Module When​ ​installing​ ​or​ ​removing​ ​a​ ​module​ ​from​ ​your​ ​case​ ​always​ ​turn​ ​off​ ​the​ ​power​ ​to​ ​the​ ​case​ ​and disconnect​ ​the​ ​power​ ​cable.​ ​Failure​ ​to​ ​do​ ​so​ ​may​ ​result​ ​in​ ​serious​ ​injury​ ​or​ ​equipment​ ​damage. Ensure​ ​the​ ​10-pin​ ​connector​ ​on​ ​the​ ​power​ ​cable​ ​is​ ​connected​ ​correctly​ ​to​ ​the​ ​module​ ​before proceeding.​ ​The​ ​red​ ​stripe​ ​on​ ​the​ ​cable​ ​must​ ​line​ ​up​ ​with​ ​the​ ​-12V​ ​pins​ ​on​ ​the​ ​module’s​ ​power connector.​ ​The​ ​pins​ ​are​ ​indicated​ ​with​ ​the​ ​label​ ​-12V,​ ​a​ ​white​ ​stripe​ ​next​ ​to​ ​the​ ​connector,​ ​the words​ ​“red​ ​stripe”,​ ​or​ ​some​ ​combination​ ​of​ ​those​ ​indicators. Page​ ​3

Most​ ​modules​ ​will​ ​come​ ​with​ ​the​ ​cable​ ​already​ ​connected​ ​but​ ​it​ ​is​ ​good​ ​to​ ​double​ ​check​ ​the orientation.​ ​Be​ ​aware​ ​that​ ​some​ ​modules​ ​may​ ​have​ ​headers​ ​that​ ​serve​ ​other​ ​purposes​ ​so ensure​ ​the​ ​cable​ ​is​ ​connected​ ​to​ ​the​ ​right​ ​one. The​ ​other​ ​end​ ​of​ ​the​ ​cable,​ ​with​ ​a​ ​16-pin​ ​connector,​ ​connects​ ​to​ ​the​ ​power​ ​bus​ ​board​ ​of​ ​your Eurorack​ ​case.​ ​Ensure​ ​the​ ​red​ ​stripe​ ​on​ ​the​ ​cable​ ​lines​ ​up​ ​with​ ​the​ ​-12V​ ​pins​ ​on​ ​the​ ​bus​ ​board. On​ ​Intellijel​ ​power​ ​supplies​ ​the​ ​pins​ ​are​ ​labelled​ ​with​ ​the​ ​label​ ​“-12V”​ ​and​ ​a​ ​thick​ ​white​ ​stripe: If​ ​you​ ​are​ ​using​ ​another​ ​manufacturer’s​ ​power​ ​supply,​ ​check​ ​their​ ​documentation​ ​for instructions. Page​ ​4

Once​ ​connected,​ ​the​ ​cabling​ ​between​ ​the​ ​module​ ​and​ ​power​ ​supply​ ​should​ ​resemble​ ​the picture​ ​below: Before​ ​reconnecting​ ​power​ ​and​ ​turning​ ​on​ ​your​ ​modular​ ​system,​ ​double​ ​check​ ​that​ ​the​ ​ribbon cable​ ​is​ ​fully​ ​seated​ ​on​ ​both​ ​ends​ ​and​ ​that​ ​all​ ​the​ ​pins​ ​are​ ​correctly​ ​aligned.​ ​If​ ​the​ ​pins​ ​are misaligned​ ​in​ ​any​ ​direction​ ​or​ ​the​ ​ribbon​ ​is​ ​backwards​ ​you​ ​can​ ​cause​ ​damage​ ​to​ ​your​ ​module, power​ ​supply,​ ​or​ ​other​ ​modules. After​ ​you​ ​have​ ​confirmed​ ​all​ ​the​ ​connections,​ ​you​ ​can​ ​reconnect​ ​the​ ​power​ ​cable​ ​and​ ​turn​ ​on your​ ​modular​ ​system.​ ​You​ ​should​ ​immediately​ ​check​ ​that​ ​all​ ​your​ ​modules​ ​have​ ​powered​ ​on and​ ​are​ ​functioning​ ​correctly.​ ​If​ ​you​ ​notice​ ​any​ ​anomalies,​ ​turn​ ​your​ ​system​ ​off​ ​right​ ​away​ ​and check​ ​your​ ​cabling​ ​again​ ​for​ ​mistakes.

Controls 1. Buttons​ ​-​ ​Accesses​ ​different​ ​parameters​ ​of​ ​the​ ​Mutamix​ ​depending​ ​on​ ​whether​ ​the module​ ​is​ ​in​ ​its​ ​default​ ​Main​ ​Mode​,​ ​or​ ​in​ ​X​-​Mode​.​ ​The​ ​default​ ​behaviour​ ​causes channels​ ​to​ ​mute​ ​when​ ​a​ ​button​ ​is​ ​pressed​ ​and​ ​solo​ ​when​ ​a​ ​button​ ​is​ ​double​ ​pressed. 2. Faders​ ​-​ ​Adjusts​ ​the​ ​level​ ​of​ ​signal​ ​on​ ​a​ ​particular​ ​channel. 3. OUTPUT​ ​BUS​ ​Switches​ ​-​ ​Selects​ ​between​ ​BUS​ ​A​,​ ​BUS​ ​B​,​ ​and​ ​BUS​ ​C​​ ​as​ ​the​ ​output destination​ ​for​ ​a​ ​channel. 4. BUS​ ​A​ ​Attenuator​ ​-​ ​Used​ ​to​ ​reduce​ ​the​ ​signal​ ​level​ ​from​ ​the​ ​BUS​ ​A​ ​output.​ ​When​ ​fully clockwise​ ​the​ ​signal​ ​is​ ​not​ ​attenuated. 5. BUS​ ​C​ ​Attenuator​ ​-​ ​Reduces​ ​the​ ​signal​ ​level​ ​of​ ​the​ ​BUS​ ​C​ ​output.​ ​Fully​ ​clockwise means​ ​the​ ​signal​ ​is​ ​not​ ​attenuated. Inputs​ ​and​ ​Outputs A. INPUTS​ ​-​ ​Allows​ ​input​ ​of​ ​an​ ​audio​ ​or​ ​CV​ ​signal​ ​to​ ​a​ ​channel. B. MUTE​ ​CTRL​ ​/​ ​X-MODE​ ​FUNCTIONS​ ​-​ ​Sending​ ​gate​ ​or​ ​trigger​ ​signals​ ​to​ ​these​ ​inputs causes​ ​muting​ ​while​ ​in​ ​Main​ ​Mode​,​ ​and​ ​triggers​ ​specific​ ​functions​ ​while​ ​in​ ​X-Mode​. C. BUS​ ​OUTPUTS​ ​-​ ​Provides​ ​three​ ​selectable​ ​outputs​ ​from​ ​the​ ​Mutamix​ ​with​ ​attenuation on​ ​BUS​ ​A​ ​and​ ​BUS​ ​C Page​ ​7

Instructions While​ ​in​ ​Mutamix’s​ ​default​ ​Main​ ​Mode​,​ ​it​ ​functions​ ​as​ ​an​ ​audio​ ​and​ ​CV​ ​mixer.​ ​It​ ​can​ ​even​ ​be used​ ​to​ ​process​ ​both​ ​types​ ​of​ ​signal​ ​simultaneously​ ​due​ ​to​ ​the​ ​flexible​ ​bus​ ​routing​ ​architecture. Simply​ ​plug​ ​your​ ​signals​ ​into​ ​the​ ​inputs,​ ​select​ ​an​ ​OUTPUT​ ​BUS​ ​using​ ​the​ ​switches​ ​at​ ​the bottom​ ​of​ ​each​ ​channel,​ ​and​ ​make​ ​the​ ​necessary​ ​connections,​ ​then​ ​adjust​ ​your​ ​fader​ ​levels​ ​as desired. Channels​ ​can​ ​be​ ​muted​ ​by​ ​pressing​ ​their​ ​associated​ ​buttons​ ​at​ ​the​ ​top,​ ​or​ ​soloed​ ​by​ ​double pressing.​ ​Arrangements​ ​of​ ​mutes​ ​can​ ​be​ ​saved​ ​by​ ​holding​ ​the​ ​SAVE​ ​button​ ​for​ ​approximately​ ​1 second,​ ​until​ ​the​ ​X-MODE​ ​LED​ ​flashes,​ ​and​ ​then​ ​pressing​ ​the​ ​button​ ​where​ ​you​ ​want​ ​to​ ​save this​ ​arrangement​ ​as​ ​a​ ​preset.​ ​These​ ​arrangements​ ​can​ ​then​ ​be​ ​loaded​ ​by​ ​holding​ ​the​ ​LOAD button​ ​for​ ​approximately​ ​one​ ​second​ ​and​ ​then​ ​pressing​ ​the​ ​button​ ​with​ ​the​ ​desired​ ​preset. These​ ​presets​ ​can​ ​be​ ​saved​ ​to​ ​EEPROM​ ​for​ ​recall​ ​after​ ​power​ ​cycling​ ​by​ ​holding​ ​the​ ​SAVE button​ ​for​ ​a​ ​few​ ​seconds,​ ​until​ ​it​ ​flashes​ ​rapidly. The​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs​ ​will​ ​mute​ ​channels​ ​when​ ​they​ ​receive​ ​a​ ​gate​ ​or trigger​ ​signal.​ ​Their​ ​behaviour​ ​will​ ​depend​ ​on​ ​the​ ​GATE/PULSE​ ​settings.​ ​Pressing​ ​and​ ​holding the​ ​GATE​ ​or​ ​PULSE​ ​buttons​ ​will​ ​cause​ ​the​ ​channel​ ​fader​ ​LEDs​ ​to​ ​light​ ​up​ ​if​ ​they​ ​are​ ​in​ ​the selected​ ​mode.​ ​For​ ​example​ ​if​ ​you​ ​hold​ ​the​ ​GATE​ ​button,​ ​the​ ​channels​ ​set​ ​to​ ​GATE​ ​mode​ ​will light​ ​up. Channels​ ​in​ ​GATE​ ​mode​ ​will​ ​mute​ ​while​ ​the​ ​signal​ ​on​ ​their​ ​respective​ ​input​ ​is​ ​high.​ ​Channels​ ​in PULSE​ ​mode​ ​will​ ​cause​ ​toggle​ ​between​ ​being​ ​muted​ ​and​ ​unmuted​ ​on​ ​every​ ​trigger​ ​received​ ​on their​ ​input.​ ​GATE​ ​mode​ ​is​ ​optimized​ ​for​ ​square​ ​wave​ ​LFOs​ ​and​ ​sustained​ ​gate​ ​notes,​ ​while PULSE​ ​is​ ​meant​ ​to​ ​be​ ​used​ ​with​ ​short​ ​momentary​ ​triggers​ ​or​ ​pulses. Holding​ ​down​ ​X-MODE​ ​enters​ ​the​ ​other​ ​mode​ ​of​ ​the​ ​Mutamix,​ ​which​ ​changes​ ​the​ ​behaviour​ ​of the​ ​buttons​ ​and​ ​the​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs.​ ​The​ ​buttons​ ​now​ ​instantly​ ​recall saved​ ​presets​ ​when​ ​pressed.​ ​Furthermore,​ ​the​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs​ ​have now​ ​switched​ ​from​ ​providing​ ​MUTE​ ​CTRL​ ​to​ ​their​ ​X-MODE​ ​FUNCTIONS.​ ​The​ ​respective functions​ ​of​ ​each​ ​input​ ​is​ ​displayed​ ​in​ ​blue​ ​below​ ​the​ ​input​ ​jacks.​ ​These​ ​functions​ ​can​ ​also​ ​be accessed​ ​by​ ​double​ ​tapping​ ​their​ ​associated​ ​button. Connecting​ ​a​ ​clock​ ​signal​ ​to​ ​the​ ​CLK​ ​input​ ​causes​ ​Mutamix​ ​to​ ​step​ ​through​ ​saved​ ​presets​ ​on each​ ​clock​ ​pulse.​ ​RESET​ ​will​ ​jump​ ​to​ ​the​ ​first​ ​preset,​ ​DIR​ ​will​ ​change​ ​the​ ​direction​ ​Mutamix steps​ ​through​ ​presets,​ ​RANDOM​ ​will​ ​jump​ ​to​ ​a​ ​random​ ​preset,​ ​INV​ ​will​ ​invert​ ​the​ ​current​ ​mute state​ ​of​ ​all​ ​channels,​ ​and​ ​MUTE-ALL​ ​will​ ​mute​ ​or​ ​unmute​ ​all​ ​channels.​ ​The​ ​number​ ​of​ ​presets used​ ​in​ ​this​ ​sequence​ ​can​ ​be​ ​set​ ​by​ ​holding​ ​down​ ​the​ ​PULSE​ ​button​ ​and​ ​then​ ​selecting​ ​the​ ​last preset​ ​to​ ​be​ ​used.

Main​ ​Mode Mutamix​ ​initializes​ ​in​ ​its​ ​default​ ​Main​ ​Mode,​ ​indicated​ ​by​ ​the​ ​X-MODE​ ​LED​ ​being​ ​off.​ ​In​ ​this mode,​ ​Mutamix​ ​functions​ ​as​ ​a​ ​fairly​ ​standard​ ​audio/CV​ ​mixer​ ​with​ ​muting​ ​activated​ ​by​ ​the buttons,​ ​but​ ​also​ ​the​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs.​ ​In​ ​this​ ​mode,​ ​the​ ​buttons perform​ ​different​ ​functions​ ​depending​ ​on​ ​how​ ​they​ ​are​ ​pressed. Button​ ​Single​ ​Press​ ​-​ ​Mutes​ ​or​ ​unmutes​ ​the​ ​respective​ ​channel. Button​ ​Double​ ​Press​ ​-​ ​Puts​ ​a​ ​channel​ ​in​ ​solo​ ​and​ ​mutes​ ​all​ ​other​ ​channels.​ ​Pressing​ ​other buttons​ ​adds​ ​them​ ​to​ ​the​ ​solo​ ​state,​ ​and​ ​double​ ​pressing​ ​any​ ​button​ ​exits​ ​the​ ​solo​ ​mode. Double​ ​pressing​ ​a​ ​button​ ​will​ ​also​ ​exit​ ​any​ ​menu​ ​state. Held​ ​Button​ ​Press​ ​-​ ​Holding​ ​a​ ​button​ ​for​ ​approximately​ ​1​ ​second​ ​activates​ ​the​ ​labelled functionality​ ​of​ ​a​ ​button. X-MODE​ ​-​ ​Enters​ ​X-Mode​,​ ​changing​ ​the​ ​functionality​ ​of​ ​the​ ​buttons​ ​and​ ​MUTE CTRL/X-MODE​ ​FUNCTIONS​ ​inputs. SAVE​ ​-​ ​Saves​ ​current​ ​muting​ ​configurations​ ​and​ ​GATE/PULSE​ ​settings​ ​as​ ​a​ ​preset. Holding​ ​this​ ​button​ ​allows​ ​the​ ​selection​ ​of​ ​a​ ​button​ ​as​ ​a​ ​slot​ ​to​ ​save​ ​a​ ​preset.​ ​Then​ ​press the​ ​button​ ​to​ ​save​ ​a​ ​preset​ ​to​ ​the​ ​desired​ ​button.​ ​A​ ​preset​ ​can​ ​be​ ​saved​ ​to​ ​each​ ​of​ ​the six​ ​buttons.​ ​These​ ​presets​ ​can​ ​be​ ​saved​ ​to​ ​EEPROM​ ​for​ ​recall​ ​after​ ​power​ ​cycling​ ​by holding​ ​the​ ​SAVE​ ​button​ ​until​ ​it​ ​flashes​ ​rapidly.​ ​Channel​ ​fader​ ​LEDs​ ​of​ ​buttons​ ​with saved​ ​presets​ ​will​ ​light​ ​up. LOAD​ ​-​ ​Allows​ ​selection​ ​of​ ​a​ ​preset​ ​to​ ​be​ ​loaded.​ ​If​ ​a​ ​button​ ​has​ ​a​ ​saved​ ​preset,​ ​its channel​ ​fader​ ​LED​ ​will​ ​light​ ​up. KILL​ ​-​ ​Mutes​ ​all​ ​channels.​ ​The​ ​LEDs​ ​will​ ​all​ ​blink​ ​rapidly​ ​to​ ​indicate​ ​kill​ ​is​ ​active.​ ​Press any​ ​button​ ​to​ ​exit​ ​this​ ​mode. GATE​ ​-​ ​Causes​ ​the​ ​channel​ ​fader​ ​LEDs​ ​of​ ​any​ ​channels​ ​set​ ​to​ ​GATE​ ​mode​ ​to​ ​light​ ​up. Channels​ ​set​ ​to​ ​GATE​ ​mode​ ​will​ ​mute​ ​if​ ​a​ ​gate​ ​sent​ ​to​ ​the​ ​channel’s​ ​MUTE CTRL/X-MODE​ ​FUNCTIONS​ ​input​ ​is​ ​high,​ ​and​ ​unmute​ ​while​ ​the​ ​gate​ ​is​ ​low. Page​ ​9

PULSE​ ​-​ ​Causes​ ​the​ ​channel​ ​fader​ ​LEDs​ ​of​ ​any​ ​channels​ ​set​ ​to​​ ​PULSE​ ​mode​ ​to​ ​light up.​ ​Channels​ ​set​ ​to​ ​PULSE​ ​mode​ ​will​ ​toggle​ ​between​ ​muted​ ​and​ ​unmuted​ ​if​ ​a​ ​trigger​ ​or pulse​ ​is​ ​sent​ ​to​ ​the​ ​channel’s​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​input. Page​ ​10

X-Mode Holding​ ​the​ ​X-MODE​ ​button​ ​until​ ​the​ ​corresponding​ ​LED​ ​lights​ ​up​ ​brings​ ​the​ ​Mutamix​ ​into X-Mode​,​ ​enabling​ ​the​ ​sequencing​ ​of​ ​presets.​ ​Now​ ​the​ ​functions​ ​of​ ​the​ ​buttons​ ​have​ ​changed, and​ ​the​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs​ ​perform​ ​their​ ​X-MODE​ ​FUNCTIONS​, displayed​ ​in​ ​the​ ​solid​ ​blue​ ​bar​ ​below​ ​their​ ​jacks.​ ​Be​ ​sure​ ​to​ ​save​ ​presets​ ​before​ ​entering X-Mode​ ​or​ ​there​ ​will​ ​be​ ​no​ ​presets​ ​to​ ​load​ ​or​ ​sequence. Button​ ​Single​ ​Press​ ​-​ ​Recalls​ ​the​ ​preset​ ​of​ ​channel​ ​mute​ ​and​ ​GATE/PULSE​ ​settings​ ​saved​ ​to a​ ​button. Button​ ​Double​ ​Press​ ​-​ ​Performs​ ​the​ ​channel’s​ ​associated​ ​X-Mode​ ​action​ ​displayed​ ​in​ ​the​ ​blue bar​ ​below​ ​the​ ​MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​inputs. Held​ ​Button​ ​Press X-MODE​ ​-​ ​Exits​ ​X-Mode​ ​and​ ​returns​ ​to​ ​Main​ ​Mode PULSE​ ​-​ ​Allows​ ​sequence​ ​length​ ​to​ ​be​ ​selected​ ​by​ ​pressing​ ​one​ ​of​ ​the​ ​six​ ​buttons.​ ​The channel​ ​fader​ ​LED​ ​of​ ​the​ ​last​ ​step​ ​will​ ​blink.​ ​Preset​ ​button​ ​slots​ ​outside​ ​of​ ​the​ ​pattern length​ ​will​ ​be​ ​ignored​ ​when​ ​presets​ ​are​ ​randomized.​ ​For​ ​example,​ ​if​ ​the​ ​sequence length​ ​is​ ​set​ ​to​ ​four,​ ​presets​ ​five​ ​and​ ​six​ ​will​ ​not​ ​be​ ​selected​ ​during​ ​randomization. Holding​ ​the​ ​SAVE​ ​button​ ​until​ ​the​ ​X-Mode​ ​LED​ ​flashes​ ​rapidly​ ​will​ ​still​ ​cause​ ​the​ ​Mutamix​ ​to save​ ​its​ ​current​ ​settings​ ​to​ ​EEPROM.​ ​This​ ​can​ ​be​ ​used​ ​to​ ​have​ ​the​ ​module​ ​initialize​ ​in​ ​X-Mode instead​ ​of​ ​its​ ​Main​ ​mode. MUTE​ ​CTRL/X-MODE​ ​FUNCTIONS​ ​can​ ​either​ ​be​ ​triggered​ ​by​ ​double​ ​pressing​ ​buttons​ ​or​ ​by sending​ ​a​ ​gate,​ ​trigger,​ ​or​ ​clock​ ​signal​ ​to​ ​their​ ​inputs. CLK​ ​-​ ​Advances​ ​through​ ​saved​ ​presets. RESET​ ​-​ ​Resets​ ​to​ ​preset​ ​one​ ​upon​ ​receiving​ ​a​ ​gate​ ​or​ ​trigger​ ​signal. DIR​ ​-​ ​Changes​ ​direction​ ​of​ ​preset​ ​sequencing. RANDOM​ ​-​ ​Selects​ ​a​ ​random​ ​preset​ ​from​ ​within​ ​the​ ​sequence​ ​length. INV.​ ​-​ ​Inverts​ ​the​ ​current​ ​mute​ ​state​ ​of​ ​Mutamix. MUTE-ALL​ ​-​ ​Mutes​ ​or​ ​unmutes​ ​all​ ​channels. Page​ ​11

Rear​ ​Jumpers LINK​ ​-​ ​By​ ​removing​ ​the​ ​jumpers,​ ​this​ ​header​ ​allows​ ​the​ ​connection​ ​of​ ​a​ ​Linix​ ​VCA​ ​using​ ​a 12-pin​ ​ribbon​ ​cable.​ ​Connecting​ ​the​ ​two​ ​modules​ ​normals​ ​the​ ​outputs​ ​of​ ​the​ ​Linix​ ​to​ ​the​ ​inputs of​ ​the​ ​Mutamix.​ ​Connecting​ ​cables​ ​to​ ​the​ ​Linix​ ​outputs​ ​will​ ​not​ ​break​ ​this​ ​normalling.​ ​However, connecting​ ​signals​ ​to​ ​the​ ​Mutamix​ ​inputs​ ​will​ ​break​ ​this​ ​normalling.​ ​This​ ​can​ ​be​ ​useful​ ​for splitting​ ​a​ ​signal,​ ​for​ ​example​ ​to​ ​create​ ​a​ ​wet/dry​ ​mix.​ ​Note​ ​that​ ​because​ ​the​ ​Linix​ ​sums​ ​its inputs​ ​to​ ​channel​ ​six,​ ​Mutamix​ ​will​ ​in​ ​turn​ ​receive​ ​the​ ​sum​ ​of​ ​all​ ​Linix​ ​signals​ ​on​ ​channel​ ​six. INPUT​ ​NORMALS​ ​+5V/GND​ ​-​ ​The​ ​position​ ​of​ ​this​ ​jumper​ ​will​ ​determine​ ​the​ ​behaviour​ ​of​ ​the Mutamix​ ​faders. GND​ ​-​ ​With​ ​no​ ​input​ ​connected,​ ​Mutamix​ ​faders​ ​send​ ​no​ ​offset​ ​signal​ ​regardless​ ​of​ ​their position.​ ​If​ ​an​ ​input​ ​is​ ​connected,​ ​the​ ​fader​ ​raises​ ​the​ ​amount​ ​of​ ​input​ ​signal​ ​sent​ ​to​ ​the selected​ ​BUS​ ​output.​ ​This​ ​is​ ​the​ ​default​ ​behaviour​ ​for​ ​Mutamix​ ​faders. +5V​ ​-​ ​Mutamix​ ​faders​ ​will​ ​send​ ​a​ ​zero​ ​to​ ​five​ ​volt​ ​offset​ ​signal​ ​determined​ ​by​ ​the​ ​position of​ ​the​ ​fader.​ ​This​ ​allows​ ​the​ ​Mutamix​ ​to​ ​function​ ​as​ ​a​ ​CV​ ​step​ ​sequencer​ ​while​ ​in X-Mode​ ​for​ ​melodies,​ ​filter​ ​modulation,​ ​or​ ​other​ ​uses.​ ​Connecting​ ​an​ ​input​ ​to​ ​a​ ​channel (or​ ​step)​ ​breaks​ ​this​ ​normalling,​ ​therefore​ ​no​ ​offset​ ​will​ ​be​ ​added​ ​to​ ​the​ ​input​ ​signal​ ​and the​ ​fader​ ​will​ ​simply​ ​control​ ​the​ ​amount​ ​sent​ ​to​ ​the​ ​selected​ ​OUTPUT​ ​BUS​ ​as​ ​usual.
