ERICA SYNTHS MIDI TO CLOCK BUILD MANUAL NIDI ACTIVITY LED BLINKS WAEN NODULE THANK YOU FOR ORDERING RECEIVES NIDI MESSAGES ERICA SYNTHS MIDI TO CLOCK RERE YOU PLUG A NIDI CABLE FRON TAE NIDI OUTPUT MODULE KIT QF YOUR SEQUENCER OR DRUM NACAINE If you are true analogue enthusiast you most probably have couple of MIDI IN analogue sequencers that need to be synced to your drum machines and pa other midi controllers therefore Erica synths has developed a simple easy to build and cost effective MIDI TO CLOCK module with few inter esting features Besides direct clock output that follows BPM of the midi sequencer or drum machine it has second clock output with selectable clock division by 2 4 and 8 It has low part count and doesn t need cali bration PCB comes with pre soldered and pre programmed microcon troller Power supply circuit is diode protected so you will not kill the module in case you switch polarity of PSU cable TECHNICAL CHARACTERISTICS LED GIVES VISUAL INDICATION OF TAE CLOCK RATE TAIS 1S MAIN CLOCK OUTPUT TAAT FOLLOWS BPN OF TAE NIDI CLOCK LED GIVES VISUAL INDICATION OF TRE DIVIDED CLOCK RATE DIVIDED CLOCK OUTPUT WAERE YOU GET NIDI CLOCK DIVIDED FOR 2 4 OR 8 IN CONT POSITION NODULE RECEIVES NIDI CLOCK Panel width 6HP CONTINUOUSLY UNTIL IT 1S PRESENT IN CTRL Module depth 20mm POSITION ANALOGUE CLOCK ON TRE OUTPUT STARTS Power consumption 10mMA 12V OMA 12V AND STOPS IN LINE WITA NIDI START AND ST
