Hey guys,

If this is the totally inappropriate place to post this question, I
apologize, but I figure all of you have extensive MIDI-to-CV
experience being modular users.  I, myself, am not a stranger to
analog, but new to MIDI-to-CV.

I have an ARP Solus, and have recently acquired a Doeper MCV4.  The
issue is, regardless of what reference note I send to the MCV4, my
midi controller (an Alesis Andromeda) always triggers the ARP several
octaves  higher than what it should be.  In other words, I can only
use my Arp for doing high notes.

I've tried to adjust the range adjuster inside the MCV4, but to no
avail.  Any help would be intensely appreciated.

Thanks.

To speak the truth I have no experience with the ARP Solus but only with the
Odyssey. Provided that the CV/Gate specs of both ARPs are identical there
should be no problem to control the Solus with the MCV4. You have to set the
internal gate jumper to +U as at least the Odyssey cannot be triggered with
+5V but requires at least ~ +8V gate level. A power supply with at least 9V
(better 12V) should be used for the MCV4. The CV output of the MCV4 has to
be referenced to the midi note that corresponds to 0V CV. For this the learn
button has to pressed (LED flashes) followed by an incoming midi note on
message that corresponds to 0V CV. Pay attention that really a midi note on
message is the next message after the learn button is operated. Other midi
messages (e.g. control change, program change) will also end the learn mode
without changing the reference note ! Please refer to the MCV4 user's
manual. The trimming potentiometer inside the MCV4 should be used only for
fine adjustment of the 1V/oct provided that the CV does not fit 100% to the
CV input of the device controlled by MCV4. It should not be used for offset
correction !

Best wishes

Hi

I once had a Solus and a Odyssey for restauration on my workbench. The 
Solus I had did definitely not trigger below 9 Volts.

Excellent.  I will try switching it to +U and report back.

Thanks Dieter and Florian.

Yeah, no change with it set to +U.

What a bummer.  I am going to try and return it to Analogue Haven if
no one has any more ideas.

But, thanks for your help, guys?

Hi

It should be no problem to modify the input of the Solus a littlebit, to 
make it accept lower gate signals to. It would not hurt the Solus and 
would not change its behaviour (except its "non-behaviour")

Florian

Yeah, I decided to go the easier route and get a Kenton Pro Solo Mk
II.  Analogue Haven was cool enough to take back the MCV4.

And now, onto the next project... I am thinking of the full-on Doepfer
modular.
