Doepfer dark time with LP

Post by Raaku » Wed Feb 23, 2011 5:23 pm

Hi!

I've wanted to buy a proper old schoolish sequencer for quite some time and Doepfer's Dark Time http://www.doepfer.de/home_e.htm would be awesome, but I wonder if the Dark time's CV outs can be properly used with the LP. The Dark Time uses 1v/octave which is ok, but the dark time's cv outs output -2 to +10 volts. If I remember correctly the LP's inputs accept -5 to +5 volts, so could I damage my LP when using it with the Dark time?

Thanks

From the Dark Time manual:
- Gate 1 Out: Provides gate-signals of steps 1 – 8 (+5V)
– Gate 2 Out: Provides gate-signals of steps 9 – 16 (+5V)
– CV 1 Out: Provides control-voltage of steps 1 – 8 (0V to +1V / +2V / +5V)
– CV 2 Out: Provides control-voltage of steps 9 – 16 (0V to +1V / +2V / +5V)
– CV 1 In: Receives external control-voltage to control steps 1 – 8 (0V to +5V)
– CV 2 In: Receives external control-voltage to control steps 9 – 16 (0V to +5V)

There are 3 CV ranges that can be set depending on what resolution Vs. range you want.

Looks like it will play perfectly with the LP!!! Except for the tiny issue where the LP CV in is not exactly 1V/Octave. It is close enough for the way I would use an analog sequencer (I would not use a 5 octave range too often). LP CV pitch tracks something like .97V/Oct.
