***Producers on ItyDity are expected to be able to play or outsource: LIVE Guitar, Keys, Bass and LIVE or programmed Drums.*** For any other "niche" instrumentation requested that the artist does not want played with a synth, you will be allowed to charge the songwriter client additional fees to cover the cost of 3rd party instrumentalists, shall you NOT be able to play those yourself, and upon pre-negotiation and approval by the songwriter client. Does this sound agreeable to you?
