There are so many free impulse files for convolution reverb, amp/cab sims, and other fx available these days… a basic convolution dsp device would be amazing…especially if it could load impulse wavs from the wavetable and allow reversing, switching, and crossfading between them using pattern commands.

Said pattern commands could simply be normal DSP controls.

As an alternative you can use Freeverb Impulser-2. It’s a free open-source VST that can host 9 impulse responses simustainiously and handles automation ok.
