JoaChip has a nice little bass synth called TB4005 up at Tokyo3.
- 5 Waveforms (saw, square, triangle, sine1, sine2) with finetune control
- Filter with cutoff (20Hz/22KHz) and resonance
- Decay and length controls
- Chord control (15 different chord settings, i.e. Major5-9)
This little plug-in sound quite nice. I loved the sound I got on a Sine with Chord Ma4-7-11. It seems to act a bit funny when playing notes which are 15+ notes apart though, might be a bug.
