ArpBud designed for creating arpeggios and sequences as easy as possible.
It has two main sequencers, the interval sequencer and the pitch sequencer with unlimited number of steps for each.
You can add/remove/copy/paste steps, load other sequencers from your other projects and set step's value with either knobs or touch gestures on step buttons.
With interval sequencer, you can design your arpeggios by their halfsteps (intervals) and sequence them with by applying its container pitch sequencer's pitch value.
You can also send pitch bend, modulation and portamento MIDI control commands as well.
Every step of pitch sequencer has its own interval sequencer.
Their pitch value will be applied to interval values of its interval sequencer steps while sequencing.
For example, if you have a pitch sequencer step with pitch C4 and its interval sequencer has steps with 0, 1, 2, 3 interval values, it will be sequence C4, C#4, D4, D#4.
Pitch sequencer has two modes, edit and play. In edit mode, you can switch between the steps for editing that step's interval sequencer. In play mode, you can toggle on/off the steps.
You can also change the rate, arpeggio style and loop count.
