Classic great condition high end 90s keyboard sampler includes the following features:Effects unitThe ASR-10 offers a powerful and flexible internal effects unit, offering the capability to resample an existing sound with an effect, and to process external signals through it live. Up to 62 effects are available to be used, also including a vocoder and distortion. The effects are all programmable, and flexible configurations are available for operating in multitimbral or performance modes.SequencerThe ASR-10 sequencer has an internal 96 pulse-per-quarter-note 16 track sequencer. A 'song' was a collection of 'sequences' joined together, and users are able to jump to sequences live during a performance, in much the same way as modern software such as  allows. Songs are constructed in either a step time (note by note basis), or through live recording of the MIDI information played in.Synthesis architectureThe ASR-10 has a powerful 31 voice synthesis architecture that resembls a synthesizer rather than a sampler. After selecting a sample, the sound can further be modified by up to 3 envelopes (hardwired to pitch, filter, and amplitude), 2 filters in series, one LFO, and 15 modulation sources. Up to 8 layers of different samples can be stacked together to form an 'instrument', and up to 127 different samples available up at any one time. Each sample can be modulated by any number of modulation sources, including velocity, polyphonic aftertouch, LFOs, envelopes, footpedals, or combinations of the two patch-select buttons on the left hand side of the keyboard. These patch-select buttons(an Ensoniq trademark) allow the player to instantly recall during performance any one of four pre-programmed combinations of the eight layers to be sounded.SamplingThis keyboardhas been upgraded from 2mb to the maximum expanded memory of 16mb. The machine featured Sigma-Delta 64 times oversampling, and sampled at either 30 kHz or 44.1 kHz rates at 16 bit.The machine also has the ability to record directly to hard disk with only disk space limiting the file size. This allowed it to function as an early digital two track hard disk recorder. The recording can be made through the internal effect filter and could also record its own sequencer playing.InterfacesThe ASR-10 has available SCSI compatability for connecting to an external hard drive, and CD-ROMs. It was noticeably more versatile than the EPS samplers at the time, supporting a wider variety of hard drives, both fixed and removable, including Zip and SyQuest drives. This item  has a 3.5inch floppy drive internally.Disk driveThe ASR-10 featurs a 3.5 inch loppy disk drive used with proprietary formatted disks capable of holding up to 1640K. (The decision to go with a proprietary format was to get around the then-limitation of DOS filenames which were limited to 8 characters.) There are many computer programs that allow reading, writing, and formatting Ensoniq's disk and file system, among those made by Chicken Systems (Translator and Disk Tools), and a German programmer named Thoralt who created ensoniqfs, a filesystem plugin for . Ensoniq's architecture allows a sound to be loaded from floppy while the keyboard was operational.
