Published on Jan 3, 2013 Switched On·33 videos
Update: video re-uploaded

"Here at Switched On we love playing with new gear and talking about it even more. This time around were taking a glance at the features of Critter & Guitari's new model in their Pocket Piano series: The Bolsa Bass

*Note: Some portions of this video are inaudible on devices without good enough bass response! :)

The Bolsa Bass is made for easy hands on sequencing, MIDI interactivity, being as portable as can be, battery powered, being fun, and being a truly good sounding source for your punchy & subby bass lines.

SN 8115112

via the listing: "Chick Corea's Personal OBXA. I purchased this synthesizer from his road manager. He told me Herbie Hancock played this unit live as well.

It comes with a wicked touring Anvil case.

As far as I can tell it functions really well. It also seems very well maintained.

I am currently waiting to get it tuned up locally by EPR Electronics just to keep it properly maintained, but figured I will list it to sell in the meantime.

It has the midi upgrade.

The presets were been whiped clean before the sale to me. I left his taped notes on the unit, which can easily be removed without damaging the unit."

"The OB-Xa is a polyphonic Synthesizer with up to eight voices. Each voice inside the OB-Xa is a complete synthesizer, with two Voltage Controlled Oscillators (VCOs), two Voltage Controlled Filters (VCFs),a Voltage Controlled Amplifier (VCA), and two Envelope Generators.

The voices are arranged in two groups of four voices each, refered to as the Upper Voices and Lower Voices, respectively. Each group of voices gets control signals from its own associated control cirtcitry, which also contains the Low Frequency Oscillator for each group. There is a control circuit for the Upper Voices, and a second for the Lower Voices. Both control circuits are controlled by the OC-Xa's onboard computer.

It is a computer that looks at the keyboard and the front panel controls, and then communicates the appropriate information to the control circuits and to the voices themselves.

This particular unit has a MIDI kit installed. (see pictures)

This particular unit is missing one CM 3340. (see pictures)

The voices need tuning.

The keyboard assembly needs cleaning. (Some keys cut in and out)
