[sdiy] Seq more.

[mikas]

Hi folks,

Just finished to build my first sequencer. It's up and running, not
perfec but ...

schematics what is done here:

... some action: http://www.analogas.uzrasai.lt/2010/09/02/seq-lipdymas-4/


There is some more work to do and I need help how to do it.

1. I'll change 40106 for BC547 in GATE OUT. No help needed :)

2. How to make 16 steps? Single switch 2x8/1x16 needed. There is
unused 4001 left, and I can manage to build logic with unused 4520Q3.
But how to link CV2 to 1 and GATE OUT2 to 1? Or maybe there is other
option?

3. Can 555 handle 12V? I'd like to run all from +12V.

4. Portamento seems to work even when it's OFF. At the moment caps are
22uF and seems to be too large (portamento is too long), but will
change to 2u2F, maybe even less. Will report after try.



Many thanks in advance.
