Holy cow.

I was expecting good stuff from this developer but Reduction sounds really good. The interface is pleasantly large enough to see. The filters are top notch the fx are great as well. I realize this is a basic feature set but it sets it self apart from the pack with top tier sound quality. Thanks Dead Duck.

Hi DD, .

When I strike a key repeatedly, i can overload easily the CPU because it will keep sounding as long as Release allows.
Also, when i hit a chord, it will have the same behaviour and when stealing voices start, the sound turns weak & thin.
It's easy to overload an i7 4790 CPU hitting chords because of this. Comparing with Surge, it requires 10X CPU because of voice stacking...

I've found no preset manager, I suppose Deducktion one is to be used.
And some overdrive would be useful.

Reducktion has been updated to version - this bug-fix release addresses problems with 'stuck' notes in the sequencer.

Hi, in the 32-bit-version, with preset "LD Buzzy Lead", when pressing D2 (50), there is a loud beep! I tested this with Cantabile 2.0, Tobybear Minihost and Vsthost (Seib). This does not happen with the 64-bit-version.

Thanks for reporting; this should be fixed in version

Reducktion has been updated to version - this bug-fix release addresses audio overloads in the 32-bit version.

Reducktion has been updated to version - this fixes a bug in the sequencer where a note would be skipped if played against a step with a velocity of 0.
