Then I guess your issue must be that the keyboard sends modwheel events without you noticing (either randomly, or because you're touching the modwheel without realizing). If the modwheel was resting in a low position and you touch it inadvertently, your keyboard then sends a low CC value (between 0 and 63), and since it is mapped to tremolo, then tremolo turns off.

If you don't want that to happen, either remove it from your MIDI Mappings, or experiment with the option "Set parameter (with soft takeover)" (find the button labeled "Set" in MIDI Mappings). Or simply push the modwheel up when you do want tremolo.

The Freeze filter is the snowflake icon in the icons toolbar next to Save/Copy/Paste/A/B etc.

Thanks for the reply, Alexis. I do have the tremolo on/off mapped to the mod wheel. I've experimented with settings on the Viscount which I think affect sending the on/off cc's but it doesn't seem to make a difference. Also, where do I find the Freeze Filter? Thanks again.

Regarding the tremolo turning off unexpectedly, you may want to check your MIDI Mappings : perhaps your device sends some MIDI CC that is mapped to the tremolo effect. Also make sure the Freeze filter is turned off.

Pianoteq Glitches?

I save my Rhodes and Wurlitzer programs on an iPad with tremolo turned on. Often though when calling up these programs from my keyboard (Viscount Legend One 73) more often than not they come up with the tremolo off. I then have to switch to another program on the Viscount and switch back to see if the tremolo works the next time. If I minimize the open window on the iPad I can bring up the Pianoteq window and quickly switch to an adjacent program & switch back and it comes up correctly, but this often requires more time than I have in a live situation. Is there a setting in Pianoteq where I can remedy this problem? Another glitch that sometimes happens is that Pianoteq will quit working. Then I need to disconnect the iPad from the Viscount and it starts working again upon reconnecting. I have Pianoteq set to MIDI channel 5 but don't know of a setting that will filter out all other channels, in case the buffer is overloading. Does anyone else experience this problem and have you found a way to correct these two glitches? Thanks.
