"Mail me at rklinkenberg(at)gmail(dot)com for more info on the card."

"Card is back in stock and I made some small improvements:

- New PCB layout, easier to assemble.
- Trimmers for the 1,2V/oct adjustment (portamento) are reachable from the side. No need to take of the frontpanel anymore.
- Sequencer can be triggered by the LFO. This was already possible on the old card by moving a jumper. But now it's a switch position on the frontpanel.
- Envelope generator can be triggered by the LFO.
- Sync input Sync the 208's pulser to an external sync source
- Limited Purple edition ;-)

EDIT: everyone who's interested can email me at rklinkenberg(at)gmail(dot)com stating Buchla Aux Card in the description.
Price for a pre build unit is 400 euro ex vat(if applicable)

Here a description of the functions of the card.This is the new card (4 layer pcb with mostly SMD components)

- 8-step sequencer, clocked by either the pulser or the 208 sequencer’s switches. A switch for selecting 1 alternative step length (for example 7 step)
- LFO, 0.02Hz into audio range, with frequency CV input
- Portamento, on the CO or on both the CO and the MO.
- Envelope generator with ADSR, looped, and LFO modes, plus level control and decay time CV in
- And then some....see manual."
