Yamaha TQ5 For Sale. Its a MIDI synthesizer module and sequencer in 1 box. But it's no ordinary workstation - this synth features Yamahas FM sound synthesis first made famous in its Yamaha DX-7. This box is 8 part multimtimbral and 8 voice polyphonic so it allows for 8 separate tracks / channels of 4 operator FM synth sounds. These sounds are like what you would get out of the DX100, DX11, DX21, DX27, TX81z, YS100, YS200, FB01, etc. Not exactly DX7 sounds due to a slightly different architecture, but very close. There's also a built in effects processor and functions for wind and guitar MIDI controllers. We prefer FM synths for sharp basses, brass, bells and clangs, but it's capable of a lot more. We've used this as a drum module as well - the preset FM percussion sounds are great! Not only is this a really cool piece of gear, it's also a work of art and a great conversation piece!
