Roland JX-8P Here's some presets that control a Roland JX-8P, but only if it's set to receive on channel 9 (sorry). JX Quick Edit The most important functions all in one preset! (The JX comes pretty close to a TB-303 then!) JX DCO-VCF All oscillator and filter parameters. JX LFO-ENV All VCA, LFO and envelope parameters. Diemo Schwarz schwarz@ircam.fr
