Milton's dad was too preoccupied in Milton's scornful teenage years to answer this the first time and I'm sorry for that. That kid's driving me nuts. Short form answer: yes Longer: You can use a sequential switch to gang Milton stages together - just use single or combined A/B pulse bank pattern outputs and the SS will switch upon receiving those pulses and toggle banks at that point. And having the ability to control direction makes for even more interesting patterns from multiple banks. If it's just random however, while Milton can do it, so can other sequencers - Modcan, Serge and Doepfer among them (Doepfer only if also fitted with the A-154 Sequencer Controller). What the others can't do that Milton can though is that the pulse banks can be externally disabled via a gate signal, which is kind of cool in this scenario because you can enter another point of unpredictability into the mix. An external signal to that input will turn the pulse banks on and off as that gate changes state. Not trying to be one of those 'mine is best' guys however, in a true analog environment, the Doepfer MAQ would probably also yield some way' unpredictable patterns as each bank can be set for independent direction. In this scenario, you simply use the third bank as the advancing pulse source for the sequential switch - just dial up full voltage from a given stage to create a gate signal. The only caveat to this being in using the Deopfer SS (there may be others that are also effected by this), in order to operate correctly it requires a TRIGGER input to advance, not a gate. There are ways of doing this, including another Doepfer module, the A165 Trigger Modifier or taking the pulse out of an Analogue Systems Gate delay set to no delay. I've even created pulses form gates by using it to trigger an A/R envelope generator set to a short transient. But this is entering into the whole 'how much random is enough' argument which I feel is the next most overrated synth gripe after VCO stability. bottom line: there are a few ways of doing this. Another interesting optionis using a totally independent trigger source for advancing the sequential switch. I simply gang that through an AND gate with the same clock advancing the the sequencer for the sync. Much fun.
