Yamaha DX21
Released in 1985The DX21 is a 4-operator FM synth with a 61-note keyboard. It has no velocity sensitivity, and is rather like a DX100 but with full-sized keys. It has a built-in chorus effect, and the ability to split and layer programs.

We stock both NEW and USED parts; all used electronic parts are tested and guaranteed working.
This listing reflects our current inventory and is updated in real time. If a part is shown as Out of Stock, we typically don't know when or if we might have it again - but click on the part for more info, and then you will be able to sign up for an alert when we do have it available again. By including out of stock parts in our listings, we hope to offer customers a more complete and useful resource.
We cannot diagnose repair issues by phone or email. For technical questions, we suggest posting on our Forums, where our techs - as well as other users - can offer help.
