OldSynths

Hi all...

i have recently got an ARP Axxe MK1 ... i was testing the synth but i
ofund something that i don't know if this is normal.

1. When i turn ON the RANDOM S&H switch and the "RELEASE" slider at
middle (more or less) position, and when i depress a note the release
goes to 0 volt. The release don't sustain the note.

2. Also if i play the notes normally and i add PORTAMENTO this doen't
affect the sound. The PORTAMENTO looks like it works like a S&H LAG
when i add S$H to the VCO or VCF. Is this is normal ?

3. The other thing that i note is when i hold a note and swith the
NOISE to ON position the tune goes up a little.

4. The synth works very well if the swith is in OFF position.

5. I already check and clean the switch and traces and everything
seems to be fine. I clean all the flux between traces and replaced
tantalum caps with a new ones. PSU restored with new caps, ic
regulator and power transitors. Sliders cleaned and lubricated.

5. Anyone know what could be the problem ?

The AXXE manual don't said anything about that. so i suspect that
there's is a problem with S&H switch.

If anyone have an idea about the decribed problem let me know.

Regards
