Problem when loading presets: Getting randomly errors like monophony and latency

[fdohb]

Hello:

I'm having problems with the Analog Laboratory 49.

Sometimes when I load a preset, I start to play and get errors like:

- The sound is monophonic instead of polyphonic, so I have to reload the presets and then it works fine.
- A notorious latency when I play the first note with a just loaded preset.

Has anyone experimented something similar? I'm using it with Ableton Live 9.
It's really important for me to fix this because I'm using it in live shows where there can be no errors.

Thanks a lot.
Fernando.
