Good point beaumont, the quicksilver upgrade gives awesome features, I was looking into getting it done to my Devil Fish, but unfortunately it uses a different memory storage chip to the original one and this would mean I wouldn’t be able to use the 32 Memory Bank modification which gives the ability to switch between patterns before they reach their end via a set of toggle switches and button, and thats something I use extensively to improvise adding fills and single notes on the fly, and now with the Audio/CV in to memory bank mod it is possible to switch between 4 banks using LFOs,Triggers,Audio sources etc etc.

Anyway getting to the point~
The Devil Fish MIDI in/out system works fine synced up with my A4 being able to stop playback and write patterns in the Devil Fish, so that could be another option too.

There are some exciting developments for the MIDI in/out system Robin is working on at the moment. Called ‘Dynamic Bank/Channel switching’ this is similar to the Audio/CV in to memory bank mod and those inputs can also be used with it. Basically it gives the ability to dynamically switch between 4 incoming MIDI channels which can have note data, controller data for Cutoff Freq, and even controllers to effect the velocity of Accented/non Accented notes at the MIDI out of the Devil Fish via a variety of options-MIDI notes/Controllers, Audio and CV in. I’m lucky enough to be Beta testing these new features and so far I’m blown away with the results (still waiting on the new MIDI firmware).

Robin has been working with and modifying the TB-303 since around 1990, he also installs the Quicksilver 303 upgrade with an isolated USB (i think to reduce noise). He would be the only one who I would contact for ANY help regarding the TB-303.
