[sdiy] Sequencer Idea

[modlar at gmx.de]

Hi all,

isn't this exactly the way, J. Haibles voltage controlled "divide by N"
module works ?
By the way, you can find another possibility on : 
http://www.analog-synth.de/synths/trautonium/traut.htm
In the lower half of the site, you will find a little schematic around a 
4024/40106/4082. This is a switchable division by N, but it just gives
a short pulse after each n'th triggerstep.
(just take the lower part of the schem, the upper part (integrator) is 
used for generating a subharmonic saw-signal)
