Please, reed the comments in
the pictures area below for more technical details. The
accordion has been serviced at the Accordion Gallery and
looks,feels, and sounds great. The new owner will enjoy a
well built instrument with smooth mechanics and beautiful
tone. The MIDI will open a
whole new world for orchestration and musical expression. The
microphones can be used independent of the MIDI.
You can play this accordion as acoustic instrument without any
electronics. With any amplifier you can get the benefit of full
orchestration using the built-in sound card and microphones. In
case you wish to use an additional external MIDI module all you
need to do is connect it to the MIDI OUT port of the power
supply.
Call 973-219-9259 with any questions.



The MIDI controller is programmed.
Through the gill panel the performer can recall any preset,
activate bellows dynamics,
turn on/off each MIDI channel etc. The accordion can be played with
the internal sound card without additional MIDI module.
