What John said is basically the easiest way.

Another, less elegant, approach is to use the vertical clock and the ABCD out. Because the vertical clock can only step in one direction, you'd have to use a very rapid burst of triggers to set you to the row you want. This would make a glitching sound, but if you have slow envelopes, it may be inaudible.

I may have misunderstood the original question, but I actually don't think this idea will do what JC is trying to do: two simultaneous, independent 32 note long sequences. (see original post below)

It may be good to review what those parts of the TKB are.

1) the sequencer/programmer part of the TKB is a four bank, sixteen stage sequencer; it (obviously) has four individual CV outs. It has a pulse out for each of the sixteen stages and has lots of features beyond the clock forward input such as: reset, random, hold, up/down (ie, reverse), and a key select/deselsect switch.

2) The vertical clock input merely clocks a very simple four stage sequencer, and the resulting ABCD CV output is taken from across the A B C D outputs. In this sense it is a slave sequencer to the more powerful "horizontal" sequencer. This sequencer outputs a CV based on which of the four stages (ABCD) is being addressed by the vertical clock, AND which of the sixteen stages the "horizontal" sequencer programmer is being addressed at that moment.

It wouldn't be that hard to get the sequencer to for example address A stages one through sixteen, and then skip over B. This could be done by pulsing the vertical clock twice: use the stage sixteen pulse out to trigger a DTG/DSG or similar, and then sum the second pulse out with the original pulse from stage sixteen and drive the vertical clock which should advance from the A stage to the C stage. Unfortunately, when it gets back to stage sixteen, it will again advance back to stage A. So it will just bounce between A and C.

Though if you do this, now you only need one electronic switch to get your other 32 note sequence! If you have an ARP 2600 (and a spare half of a DTG/DSG or similar) you should be able to do what you are trying to do.

At least you've got me thinking!

Just revisiting this thread now after a few months.
My question is this. We can run the TKB as a one 64 stage sequencer and four 16 stage sequencers. Is it possible to run it as two 32 stage sequencers? What I mean is that it'd run through A/B for 16 steps and then run through C/D for 16 steps.

Best,
JC
