Simultaneous adjustment of pitch & filter modulation

In the HiFi Envelope editor, using adjusting the pitch & filter modulation at the same time by sweeping faders 7 & 8 together causes causes neither setting to update (or actually to update erratically). Adjusting 7 or 8 individually behaves as expected (once fader-catchup engages).

Thanks. Fixed in dev.
