Syncing DIN Sync devices to an EDP

[philip <philip.ojc@gmail.com>]

Does anyone have any ideas for syncing old roland gear like TB303s and 
TR606/808s to an EDP?

I don't need anything fancy, just for the EDP to read the BPM or the 
length of a measure.

I'd prefer not to loop the sounds from the old Roland gear, because I want 
to be able to manipulate those units in real time whilst looping guitar 
sounds on the EDP.

Any ideas would be greatly appreciated.

Thanks,

Philip
