[sdiy] MFOS SLM + TSS = LOVE?

[Gabriel Lindeborg]

Good afternoon, fellow SDIYers!

I have given some thought on how one could build Ray's SLM and 10-step 
sequencer, as an 8-step, in a portable box to our daughter, soon 
twoandahalf, and the most obvious problem is that the sequencer is built 
for ± 12 to 15V while the SLM is ± 9V. ± 9V is a nice portable voltage 
in that you can run it with two or more 9V 6LR61 or a simple power supply.

After having looked at the schematics to 10SS 
(http://www.musicfromouterspace.com/analogsynth/TENSTEPSEQUENCER/TENSTEPSEQUENCER.php) 
I think that the R1, R2, R22 and R33 would have to be adjusted down to 
three-quarters of the original value ( 9 / 12 = 3 / 4), as with the 
values of the voltage divider components R19/R21, R85/R35 and R44/R46. 
But then I get a little unsure of what more needs to be done. Power for 
logic and opamps should not be a problem but then there are other things 
that I do not get a grip on.

Is it worth it or is there a simpler sequncer that would fit better, I 
really want to just step through a number of voltage values while I send 
a gate, or possibly trig, to the envelope generators, preferably with 
the ability to extend or skip steps.
