Analogue Solutions trans-bass-xpres Roland TB-303 clone. The trans-bass-xpres contains the same analogue voice circuit as the original 303 with MIDI implementationand some extra features like noise, LFO, Overdrive and Squelch. The extra controls like cross mod and LFO of course expand the original sound palette.

Extended information

The trans-bass-xpres also uses as many analog components as possible, but many of the original goodies have been discontinued. Interestingly, there is no internal sequencer, which will invoke a massive debate on the sound, but they made the choice and are sticking with it.

The MIDI implementation is straight forward note on/off, accent (from +80 velocity level), slide (by overlapping note) and control of cut-off from velocity or a controller.
