We have released Arp-EG classic a MIDI arpeggiator plug-in. Using Arp-EG classic all the VST instrument you like and even your hardware synth (using your DAW MIDI out) can now play arp sequence.
Use the six playback mode and the four octave range, speed up or slow down your arp sync on the beat of your DAW. Control the groove using the shuffle and gate function, control the expression with the transpose function, give to each note his one velocity, play polyphonic chord or notes sequence. Assign all the parameters to your MIDI controller easily and randomly generate your arp with a single click.
