The most modern bass tones are characterized by a dynamic and complex sound obtained using different tools and recording techniques. For this reason Nembrini Audio has decided to create the Blackice Beta Gamma Bass Amplifier plugin based on modern-classic 900 watt bass guitar head and complete it with a virtual recording chain worthy of the best recording studios. This innovative bass amplifier combines a custom tuned overdrive/distortion circuit, a studio-grade VCA compressor and a flexible six band graphic equalizer. In the amp section you can blend the clean signal with the incredible Beta Gamma Distortion circuit that can morphs from tight and defined overdrive to raw and brutal distortion. A custom VCA style compressor allows you to optimize the bass signal before hitting the six band graphic equalizer carefully tuned to sculpt your bass tone. The Blackice Beta Gamma Bass Amplifier includes a complete recording chain emulation and our custom design noise gate circuit. Works as a standalone app, AudioUnit v3 effect, or Inter-App Audio effect

PolyBud is a multitrack polyrhythmic AUv3 MIDI sequencer. You can add multiple note or MIDI CC tracks to the each pattern. The note tracks has the note, velocity, gate, ratchet, probability and randomisation modes. You can set different step lengths to the each mode which would introduce polyrhythmic variations immediately. Another great feature is the each track can run in a different rate which is great for creating unique polyrhythmic sequences. Also, you can assign different MIDI channels to the each track so that you can control multiple synths within a single PolyBud pattern. The MIDI CC tracks is great for modulating the synth parameters. You can introduce polyrhythmic modulations by setting the different step lengths and different rates to your MIDI CC tracks. Also, you can set a ramp value for smoothing up the CC value changes per step. If you set the ramp value to 0% then you can have the classic sample and hold modulation. PolyBud is a MIDI app and it don't produce any sound of its own. You need to route PolyBud's MIDI out to your audio apps in order to run PolyBud. For the AUv3 plugin, you need an AUv3 host app such as AUM, Cubase, NanoStudio, ZenBeats, BeatMaker, apeMatrix etc.
