ASR-10 Musician’s Manual © 1992 Ensoniq Preface i Welcome! Congratulations and thank you for your purchase of the ENSONIQ ASR-10 Advanced Sampling Recorder, another milestone in digital sampling keyboards. The ASR-10 revolutionizes the way sampling is integrated into a workstation, by including 24-bit dynamic effects processing and allowing the stereo audio input to be monitored, sampled, and resampled through the effects. And only ENSONIQ offers all the expressive control that turns a sampler into a truly musical instrument. Sampling The ASR-10 features true stereo Sigma-Delta (one-bit) 64 times oversampling technology with a selectable sample rate of 30kHz or 44.1 kHz. Samples can be recorded from a variety of input sources including: the stereo audio inputs, the optional DI-10 Digital I/O Board (consumer AES/EBU digital interface) or the ASR-10’s own Main Audio Output (for resampling). The ASR- 10 can sample while the sequencer is playing, and can even sample its own sequencer playback. CD quality output circuitry provides state of the art playback performance. The ASR-10 has all the on-board editing functions you’ll ever need. Autolooping, volume smoothing, gain normalization, and multiple types of crossfading provide complete control over your sampled sounds. An advanced Time Compression/Expansion function allows you to change the length or tempo of a sample without affecting the pitch, a necessity for dance music or broadcast needs. Synthesis Functions Not only does the ASR-10 provide superb stereo sampling, it is also a full function synthesizer, allowing you to reshape your sampled sounds with maximum flexibility. 31 voice polyphony, multiple filters and envelopes, and a comprehensive modulation matrix gives the ASR-10 the power to manipulate your WaveSamples into many exciting new sounds. Effects The ASR-10 incorporates effects processing into a sampler in new and exciting ways — with 50 different 24-bit effect algorithms, the ASR-10 provides a complete arsenal of signal processing and conditioning tools for your use. State-of-the-art Reverbs, Chorusing, Flanging, Phasing, Distortion, Digital Delays, and Speaker Effects, will make your sampled sounds and sequenced music sound totally professional. Signal conditioning effects, like EQ, Compression, and Ducking can be used to process sounds as they are being sampled to get the perfect sound every time. The ASR-10 offers continuous audio monitoring of the stereo audio inputs on two dedicated Audio Tracks. The audio inputs can be monitored through the effects and if desired, audio input can be sampled through the effects. Audio Tracks also allow live external signals to play through the effects processor, so that you can use the ASR-10’s high quality effects on other instruments in your rig, or allow fellow musicians to plug right in and play — no mixer required! The ASR-10 also has the ability to resample sounds with effects in real time. For example: add reverb to a drum sample, resample it, then reuse the effects processor to further color your music. Sequencing The ASR-10 is also a 16-track sequencing workstation with complete mixdown capabilities. You can record and edit your performances with a wealth of creative tools. And only ENSONIQ sequencers allow you to audition your changes to decide which version to keep. This flexible combination of high fidelity sampling and synthesis, versatile effects processing, and sequencing is what makes the ASR-10 unique. Preface ASR-10 Musician’s Manual ii Audio Track Recording Capability Version 2 O.S. adds two tracks of digital audio recording capability to the ASR-10. Audio Tracks can be recorded directly into RAM (RAMTracks™) or directly to a SCSI storage device (hard disk, removable media, etc.) via the optional SP-3 SCSI Interface (DiskTracks™). Now you can combine live performances with MIDI sequenced tracks for full production recording within the ASR-10. Sing, play your guitar, blow your horn — add whatever live performances you wish. Recognizing that you want to get up and running quickly, we strongly recommend that you try the section titled “An Audio Track Tutorial” in Section 18 — Audio Track Applications to get a feel for the Audio Track recording process. Support for the Optional DI-10 Digital I/O Interface ASR-10 Version 2 supports the optional DI-10 Digital I/O Interface. When installed, the DI-10 provides direct digital input and output connection to and from the ASR-10 using RCA-type connectors. The Digital Output will provide 44.1 kHz digital output of the Main Out mix when the current effect uses a 44.1 kHz sample rate. The Digital Input can be used for direct digital sampling from an external digital audio source at 44.1 or 48 kHz. The Digital Input and Output conforms to the S/PDIF standard (Sony/Phillips Digital Interface Format). S/PDIF is a digital audio communication standard for digital hardware devices. Be sure that any digital devices used with the DI-10 conform to this standard. For more information about using the DI-10 Digital I/O Interface, refer to the DI-10 Manual. Note: If you wish to record the 44.1 kHz digital output of the ASR-10 to a DAT recorder, the DAT recorder must be able to record from its digital input at 44.1 kHz. Some older/consumer DAT recorders do not record at 44.1 kHz as a copy protection scheme: These DAT recorders will not record the ASR-10’s 44.1 kHz digital output. Additional 44.1 kHz Effect Algorithms The O.S. disk also includes 12 additional effect algorithms, designed exclusively for the ASR-10, that use the 44 .1 kHz system sample rate (note: polyphony is reduced to 23 voices). Audio Tracks recorded at the 44.1 kHz sample rate can be output directly from the ASR-10’s Digital I/O Output jack (which requires the optional DI-10 Digital I/O Interface). For a complete description of all the effect algorithms, see later in this document. Clean Up and Maintenance Only clean the exterior of your ASR-10 with a soft, lint-free, dry (or slightly damp) cloth. You can use a slightly dampened cloth (with a mild neutral detergent) to remove stubborn dirt, but make sure that the ASR-10 is thoroughly dry before turning on the power. Never use alcohol, benzene, volatile cleaners, solvents, abrasives, polish or rubbing compounds. About The Manual The Musician’s Manual is your guide to unlocking the full power of the ASR-10. At this point, you’re probably anxious to plug in your ASR-10 in and get playing. The rest of this section contains important information about power, grounding, amplification and care of the floppy drive. We recommend that you read through it, and then follow the Tutorial. The Tutorial is designed to provide step-by-step procedures for performing basic operations on the ASR-10. After the initial “I just gotta hear it” phase has passed and you’re ready to utilize the full potential of the ASR-10, please take the time to read through the sections in this manual on sampling, programming, sequencing, effects, and storage. The Musician’s Manual is designed to be used as a reference tool. Both manuals provide valuable information and tips that will speed up the learning process and ensure your maximum enjoyment of this powerful musical instrument. Preface iii Thank-you again for choosing ENSONIQ. Enjoy the music!
