*** Note *** Although mKer can run as a stand-alone app, the recommended way to use it is as an AUv3 plugin from inside a suitable AU Host app that supports MIDI Processors such as AUM, Audiobus, Cubasis etc. Please also note that mKer is a MIDI app/plugin. That means that it does not produce sound itself - it needs to be connected to an audio source that can receive MIDI. mKer is a versatile, multi-output MIDI step sequencer with an extensive range of features. These include: - 8 MIDI outputs - 64 Patterns - 16 Lanes (aka tracks) per Pattern - Independent number of Steps (1-32) and Step Size (1/64-256 beats) per Lane per Pattern - Every step can play either a single note, an interval (2 notes) or a chord (3 or 4 notes) - Lane Step parameters: Play Cycles, Skip Cycles, Play Offset Cycles, Pitch, Velocity, Probability, Offset (can be used for ‘swing’ like effects), Repeat (rachet) and Gate - A flexible Editor that includes a step entry keyboard, parameter sliders and a variety of options and utilities designed for to make the workflow intuitive and fast - 32 Clips with 1-8 Steps per Clip, 1-128 repeats per step (every clip step has one pattern) - 3 Play Modes: Pattern, Clip, Sequence (all Clips) - A Performance tab with 10 fully assignable MIDI sliders, a 12-snapshot bank and morphing function between the snapshots... - MIDI step input and real-time recording - 12-track beat generator with six genres, density, intensity and GM beat mapping ... and more!

Read full description

resonatedo is a microtonal resonator bank audio effect for iOS and macOS. It contains two sets of resonators controlled by separate keyboards. Each resonator has independent pitch (set by EDO division value of the keyboard), volume and modulation. Each resonator is a delay with feedback that contains lowpass + allpass and bandpass filters. Each set has a common "color" parameter that changes balance between these filter sets in each single resonator. The "mix" control allows crossfade from dry to fully processed signal. UI features two independent keyboards with: • 4 – 72 keys (voices, steps) per octave, each with its own ring modulator • maximum polyphony equal to the number of voices; max polyphony is 144 voices • 1 – 4 octave range, covering the frequency range of about 8 – 4200 Hz • display with note number (from C), note name, frequency (in Hz), and deviation from 12-TET (in cents) • two sections per keyboard: upper for non-sustained notes, gliding, and velocity; lower for sustained notes and modulation rate • mute button to stop/start all sound • delete/panic button to erase all notes • glide button for smooth sweeps across keyboard frequency range • modulation on/off button • slider to set initial velocity and modulation levels • slider to change velocity and modulation rates for all notes on the keyboard proportionally and to show current velocity and mod rate levels • button to toggle keyboard visibility. resonatedo supports MIDI input from external sources to control each keyboard independently.
