Hi. I have retired from playing keyboards and I have bought a Ketron SD40 module to use with my midi accordion. There is no midi control panel on the accordion, just a midi output connection on the grill and the midi transmit velocity seems to be fixed at full. Can anyone please tell me if there is any way I can decrease the velocity received within the Ketron as the sound is very harsh due to full velocity being received. I wouldn't need it to be variable, just to reduce it somewhat so it would sound not so harsh. I have tried changing velocity settings and volume pedal response but these made no difference. Any help would be much appreciated. Thank you.
