Doepfer modular vocoder full set of 7 modules consisting of:- One A129/1 VOC-A vocoder analysis section. One A129/2 VOC-S vocoder synthesis section.Three A129/3 Vocoder slew-limiters (full expansion).One A-129/4 SLC Slew limiter controller. One A129/5 VUV Voiced/unvoiced detector. Seven modules in total representing a fully expanded vocoder sub section. All modules suffer a little rash around the mounting holes and the a-129/1 has a small scratch at the top. Nice set , discontinued now and rare as hens teeth.Mounting screws and ribbon cables included. Very flexible and can be used for plenty of other things other than Vocoding , i.e. As a filter bank for instance. Selling as I'm making some hp for a big switch round , I can't stop swapping modules out I guess and I've not been using the vocoder sub section too much recently. Saying that I'll probs kick myself for selling it in a few months!I pack well and dispatch quickly , fully insured , tracked , signed for. I use Royal Mail special delivery or UPS. If I get the postage cheaper I'll refund the difference. International bidders are responsible for any other charges that are out of my control, I use global shipping so bid accordingly please.PayPal or cash on collection please. I won't split this set up so please don't ask. Remember - red stripe down , I can't be held responsible for incorrect installation into your case!!
