Be sure to add me to your favorites list New Yamaha Replacement Function Knob Dial for the RS7000, RM1X Sequencers, the A4000 / A5000 Samplers, and Data Knob Dial for the DX200 and Motif-Rack XS Midi Modules, Brand New Out of Package, Made in Japan! This is a new, just out of package condition, replacement knob / dial for several Yamaha sequencers and midi modules. Unfortunately, these are sometimes lost, so here's a brand new genuine Yamaha replacement! Specifically this part is a replacement for the function knobs (sometimes labeled 1 2 3 4 or F1 F2 F3 F4) for the RS7000 and RM1X Sequencers, as well as the A4000 and A5000 Sampler modules. Here are some cropped photos of these instruments to show the placement of this type of knob. This same part is also used as the Data dial knob for the DX200 sequencer and the Motif-Rack XS synth midi module. This is in brand new, never used condition, just out of packaging, and is a genuine Yamaha part. Price if for one (1) knob, and I have a few of these available and you can get one or more.
