it's the first time I write on this forum so first of all I want to say hello to everybody here who loves Moog's stuff

My question with Mooggerfoogers (as the main title says) is: can I use the CP-251 to control EHX pedals (the ones with the exp out jack/CV) so that I can expand their sound possibilities? CV in CP-251 works with 0-5 volts but the truth is, not all the exp out jak are actually CV too.
Electro Harmonix has a huge number of pedals that got the exp out jack and in most of cases on the manuals they write "expression out/CV" but I don't wanto to damage something...
I got the FreqBox and the CP-251 but since the combo "CP-251/MF104" is very popular I was interesed in buying Deluxe MM tap temp 550 (the green one) because its exp jack out should be (as the manual says) also a CV jack with tension of 0-5 volts. The pedal has a switch capable of change the parameter (delay, feedback, blend, depth, rate) associated with the exp out (as the MF104 but in that case, as you know, you got an exp out jack for each of the parameter on the front panel).
Do you belive that this connection could work fine? Is there someone of you who tried this trick before? And if so, what pedal did you use?
I sent an email to EHX time ago but they never answered me..
