the WHEEL DESTINATIONS panel determines the routing of the MOD X and SHAPER Y modulation signals. MOD X may be routed to any one of the following: OFF (no effect) OSC. A + B frequency, OSC. B frequency, OSC. A RWM (Pulse Width Modulation), FILT. U + L (both filters cutoff modulation) or FILT L (lower filters modulation) The Shape X WITH Y switch allows the level of MOD X to be controlled by the output of SHAPER Y for automatic vibrato etc. SHAPER Y may be routed to any one of the following: OFF (no effect) OSC. A +B frequency, OSC. B frequency, OSC. B RWM (Pulse Width Modulation), LFO RATE (MOD X frequency) or FILT L cutoff modulation. The final amount of each modulation source is governed by the relevant MOD X and SHAPER Y modulation wheel setting.
