roland xv-2020 sound module for 20k

Basic Spec & Operation

If you're a fan of JV/XV sounds, you'll probably enjoy the XV2020, as it comes packed with the types of sound that made those earlier machines so popular. In all, there are 1083 ROM waveforms, 768 ready-to-go patches, and 17 complete rhythm sets that include many of the classic Roland analogue drum sounds, as well as more conventional acoustic drum samples. The comprehensive effects section offers 40 multi-effects in addition to separate chorus and reverb. Polyphony is 64 voices, though this can sometimes be less than it seems, as Roland base their polyphony figure on how many Tones can be played back at any one time, not on how many voices. An XV2020 patch comprises between one and four Tones layered together per voice, so if you go for a four-Tone sound, the polyphony comes down to 16 voices. A bank of 256 GM sounds (the 128 main sounds plus a selection of GS type variation tones) is also included for multitimbral sequencer operation. Because the GM sound set is a standard, this set cannot be edited or modified in any way, and the drum part is always set to MIDI channel 10. Multi-effects can't be used in GM mode, but reverb and chorus are available with adjustable levels per part. The sounds are organised in a similar fashion to those on the JV1010, with one bank of user patch memories followed by four preset banks (A to D), the GM bank and two further banks that access the SRX expander cards if fitted. All the banks hold a full 128 patches except for the GM set, which includes additional 'alternative' sounds.
