"In excellent condition with its original box, this Tom Oberheim design is sort of like a MIDI guitar synth in reverse order - it lets you play keyboards and out comes the notes of a guitar chord into your existing synth or sampler.The "Strummer" listens to chords played on your MIDI keyboard and plays them back to your MIDI sound source (Synthesizer or Sampler) just as they would be played from a guitar. Not only will the chord voicing be correct, but the chords can actually be "Strummed!"
You can even change the speed and direction of your "Strums" just by changing the way you play your MIDI keyboard. Also,"Strummer" has the ability to distinguish the difference between chords and single notes, allowing you to send chords out on one MIDI channel (Distorted Guitar Sound for example) while your single notes are sent out on a different channel (i.e. Solo Sound).
By looking at such factors as the range of the guitar, the number of notes being played, chord position, and the velocity of the performance, Strummer can transform the incoming MIDI data out into performance data emulating that of a real guitarist. Performance data may be delayed, echoed, harmonized, transposed and sent back out on multiple MIDI channels.
In addition to control over strum direction and speed, the Strummer also features Chord Capture for real time single finger chords. Individual picking patterns and riffs may be assigned to a single key, for real time performance playback. You can even control the number of "strings" being strummed via keyboard velocity.
Some additional features include: Adjustable Delay and Decay Rates. Velocity Switching, Chord Voicing Variations, Chord Capture (Adjustable Single Finger Chords), Transposition of MIDI Delays (Great for MIDI Harmonizing), Ability to synchronize to MIDI Timing Clocks (External Sync), MIDI Program Change.Harmonizing), Ability to synchronize to MIDI Timing Clocks (External Sync), and MIDI Program Change."
