Mr. Mustard's Changing My Volume...Or?

Sorry, no idea why that's happening. Sounds like a quirk of the synth. You could get around it by lowering the volume on everything else. I, too, use a MO8 extensively, and often have to turn down the backing tracks while recording so as to get enough volume for the part I'm playing.

Might I suggest an alternate method...I don't ever use the MO8 in multi-timbral mode, simply because its 32-note polyphony is too limiting for more than maybe two voices at a time. So what I do is redirect each completed MIDI track to either another hardware synth (I have a rack-mounted Kurzweil for this) or to a software synthesizer (the TTS-1 is handy for this and light on CPU). Even if I plan to ultimately use a MO8 patch in the song, the alternate synths serve as placeholders during composition and tracking. Later on, when I'm happy with all the MIDI tracks, then I'll commit each of them to audio, one by one, recording via S/PDIF for maximum quality and minimal noise.

Guys, thanks for the help on this. I think at times if I click prior to the loop and hit record that the full volume is there, but if I start at or in the loop range, the volume is lower. BUT, that is not reproducible regularly. I'm considering pasting the tracks to a new song file to see if that "fixes" it. That move has worked for me before in other WTF situations. I'll post if it helps. Bitflipper, I've not been using multi-timbral mode for the same reasons you've articulated. I just record a part I'm happy with then mute the MIDI part and move on. Do you notice a big difference using S/PDIF? Great Cactus, I'd use a mixer if I had one. Perhaps one will be bestowed upon me in the near future! Short of that, I'm mixed up enough. :)

I wish my Yamaha AN1X had a digital output - I get a LOT of noise, both from the L&R outputs and the headphone output.

Sometimes, I'll also get a rhythmic ticking which only disappears if I  unplug both Midi connections at both ends, power down the AN1X, re-connect & power back up
