Analogue-sequencer

Hi Collin
will the daughterboard your doing change any of the functuality of the 303 or is it just tapping in to the ins and outs of the sequencer 
This would be of intrest to me as i use the tb's sequencer on other analog synths but it would be fun to use it on the odd digital as well

  Folks,

  I've got another project in the works, soon to be at the beta 
  testing stage. It's a tiny daughterboard to fit inside a TB303, that 
  adds midi in and out.
  This isn't another cv/gate modification. The board replaces the DAC 
  latch in the 303 with a PIC processor, and hooks into the gate, 
  accent and slide control lines. Installation requires no cutting of 
  tracks - it just needs the removal of a 16 pin IC, and three 
  resistors.
  The board will occupy the area inside the 303 shown here:
  http://www.colinfraser.com/misc/mb303-board-area.jpg

  The DAC IC is replaced with a socket for the board to fit into, and 
  the three resistors are replaced with leads to the board.
  Another 5 leads run to the midi in/out sockets. I'll probably use a 
  single 5 pin mini-din, with a Y-lead to full size sockets.
  My main purpose in designing this is to allow the simple capture of 
  TB303 patterns into P3, though it does also allow the 303 sequencer 
  to drive any external synth, and any external sequencer or keyboad 
  to drive the 303.
  Anyone here interested in a cost price beta version ?
  It'll be about 15ukp including postage.

  Cheers,
  Colin f
