Spat 5.1.0: issue with mc feature

Spat
#1

Hello T.,

Just downloaded the 5.1.0 version of the Spat, and there seems to be an issue with the mc capability and some objects.
I’ve found that spat5.cluster~ & spat5.reverb~ configured with more than 8 channels and MC activated kept on crashing max. It works fine with 8 channels, but as soon as I change the number of channels to 10, the sound gets distorted and then max crashes.

Max version: 8.0.4

Best regards,
Philippe.

Hi Philippe,

Waouh, good catch. This is a rather subtle and nasty bug that can potentially cause crashes in all reverb-related objects, regardless of @mc.
The bug is due to using a non-power of two number of channels. Which is not a great idea anyway: it is recommended to use 8 or 16 internal channels for the reverb.
This is fixed for the next release.

Thanks a lot,
T.
