The new modules sound great. I didn't see the TKB mentioned, so I
assume its production is not coming any time soon.
However, given that there may be no TKB, I was very interested in
the "A164 manual gate." I haven't seen anything regarding this
module, other than a couple of requests on this list that didn't
seem to generate a lot of enthusiasm. However, I think some kind of
a multiple manual gate a manual gate is sorely needed.
The problem, as I see it, is that it is often necessary to generate
several gates or triggers in succession to start changes in an
ongoing process, often triggering an envelope generator, advancing a
sequencer, etc. The dual trigger delay module is often too short.
The VC Decay/Gate module combined with a fixed CV to increase the
delay time is often better, and the new comparator module combined
with an envelope should be even better. Nonetheless, long trigger
delays are fiddly and time consuming to set. Sometime, manual
control is just quicker and easier. Advancing the sequencer with a
keyboard trigger sometimes works, but is sometimes not a good
solution.
The solution is some kind of easy way to generate a number of
succesive, separate triggers manually. Just a box with several
buttons, each generating a trigger or gate from a separate output.
Is this what the A-164 will be (Of course, I would prefer if each
button was also associated with a control voltage. And maybe it
could use touch plates rather than just buttons. Oh, yeah, while
we're at it, why not add some sophisticated sequencing functions.
We could call it the "TKB." Oh, sorry, I think we've already
talked about that.)
