Continuous MIDI for audio crossfade??

Hello all,

I am trying to trigger a crossfade between two external audio sources connected to a USB audio interface which is being driven by Propellerhead Reason. I can send MIDI commands from Ventuz to Reason, that 'snap' between the two mixer channels, but I would like to achieve a smooth crossfade, which would require continuous MIDI values to be sent. Does anyone have any ideas how to do this with Ventuz?

Many thanks in advance.

Paul

i guess that you are using some kind of interpolating node to generate the smooth fade values (eg. mover/linear/damper) but only press 'send' at the beginning and end of the fade.

you can connect this value with an Int node and use the 'changed' event to trigger the Midi-out 'send'

this will generate multiple midi messages per second, making the crossfade appear smooth.
