hi,
i'm trying to get my tr-626 to trigger the arp. on my polysix... the only problem is that the tr outputs +5v trig. pulses and the polysix needs -5v pulses... does anyone know if i can buy/build a simple inverter of some sort that'll allow me to "flip" the signal coming from the tr? sprry for posting here, but noone seems to pay much attention to any of the other forums.
thanks

I've tried to figure that out myself for on my TR-606. Nobody seems to know. Try going to an electrical supply store in your area, they might be able to help.

Peaceout,

Peter

just wire it negative to positive like a dc power supply can be inverted - surely ? - works with ON-OFF switches ok

thanks k, i've posted on every board i know and you're the only one who came up with anything...
the only prob. is that i know NOTHING about electronics, all i know is that the 626 outputs 0v with +5v pulses, and i need a signal which is +5v with pulses down to 0v... i read somewhere that the polysix's trigger in is the same as moog's s-trig. would just switching the wires work? the prob. is that the signal's carried on an unbalanced 1/4'' lead -- i thought those had only two wires:a ground and a signal (i.e no seperate pos./neg. wires)... could i use a balanced TRS somehow?
anyway, if you can give me specifics, that would be great, cause frankly i know dick.
thanks

This is what you need Swan:

polarity inverter

but I guess i come a little late with the answer, sorry about that

On another note, I see this thread is the only reference whatsoever about the 626 on DT. I'm about to
get one for this very trigger output, altho' I won't need an inverter as I'll hook-up to Roland's stuff.

But as far as the sounds go, how are they, anyone used one ?

cheers

Roland_TR626.zip

well thats the sounds - pretty typical for the time, not really an electronic box tho

mmm, yes, I hear what you mean. I think it can still be useable tho' straight up with some effects. But
it's apparently a circuit bending monster: decomposer/ target=_NEW>TR-626 Rhytm (de)COMPOSER

But I mainly want it to drive arps and sequencers in time to midi, so for 100$ i'll consider the stock
sounds as second thought bonus

thanks
