I am getting some false triggering on the Automat. I have the Automat being triggered by Ableton Live. Ableton Live is outputed from my computer via USB and then is connected to four Polyend Percs, daisy chained together with 5 Pin MIDI DIN cables. At the end of this chain I have another 5 Pin MIDI DIN cable connected directly to the Automat MIDI in. This setup works perfectly and I’m able to trigger 16 separate solenoids to play very complex drum patterns on my acoustic drum set with pre-programmed MIDI signals.
I also have a handful of drum triggers (mostly ddrum acoustic Pro’s but one Yamaha DT-20) on my BD, Toms, HH (closed) and snare that I route through a DDRUM DDT interface into Ableton via USB to record my drum playing via MIDI signals and then loop these signals back to the solenoids so I basically am able to loop live drum patterns on my acoustic set on the fly. This also works perfectly when I am only using the Polyend Percs, with the Automat completely disconnected.
However, the Automat does not appear to play well in conjunction with the DDRM DDTI, as when I plug the USB cable from the DDTI into my computer while the USB output to the Polyend Perc is also plugged in to the same computer, I get some false triggering on certain outputs on the Automat. It’s clear the voltage causing the false triggering is constant and not intermittent since the solenoids that are false triggering have beaters attached to them; the beaters trigger, and then never release until I unplug the DDTI USB cable.
It is a strange issue that I thought could be caused by ground loops. However, I’ve controlled for ground loops in a number of ways, such as connecting all devices mentioned above into the same outlet through a 500 watt isolation transformer, and making sure no additional connections are possible, but the problem persists. The DDTI is ungrounded (2 prong), but the Polyend Perc and Automat are grounded.
Any help would be greatly appreciated. I’d like to add additional triggers to loop more complex patterns and utilize the Automat in this way for live performances, but I dont want rogue voltages to ruin any of this equipment.
Thanks in advance.
