"The #fm_seq (portable edition) is a compact workstation that uses a special FM synthesis chip to produce tweakable sounds that can be sequenced with the included sequencer software. It uses genuine FM synthesis, not the sampled sounds you find with newer audio cards. It's 100% OPL3 compatible and is able to combine up to 36 operators so you can craft and tweak some extremely unique sounds.

Each channel features:

Main frequency (10 bits)Octave (3 bits)Note on/offSynthesis mode (FM or just additive)

Feedback (0-7, the modulator modulating itself)

For each one of the 4 oscillators: Frequency multiply (can be set to 1/2, 1 to 10, 12 or 15)Waveform (Sine, half-sine, absolute-sine, quarter-sine, alternating-sine, "camel"-sine, square and logarithmic saw)Volume (0-63, logarithmic)Attack, Decay, Sustain, Release (4 bits each, logarithmic)Tremolo (On or off)Vibrato (On or off)Sustain (On or off)Envelope scaling per key (On or off)Volume scaling per key (0-3) Vibrato depthTremolo depthPercussion mode (uses 3 channels to provide 5 percussion sounds)

You can easily maipulate the sounds in a live setting and the workstation itself is very portable. Another great thing about this workstation is that you can sit down and focus on programming your sound without the distraction of a million other programs in the background. This Item is completely unique, I built and modified both the hardware and software so this unit sounds really interesting... Watch the video if you want a good idea of what this workstation sounds like. It doesn't cover even a fraction of what this is capable of but it should give you an idea.
Everything comes setup and ready to go.

The software is incredibly easy to learn and understand....you should be able to start making music within an hour of turning the workstation on. UPDATE: A few people have asked if it is able to produce sounds similar to Commodore 64's chip music. The answer is YES....the sounds from this workstation are VERY comparable and in fact more capable since it uses 36 operators to create custom sounds. This new version is 100% compatible with all previous versions."
