Need help to use my keyboard with GPO4
I am new to GPO4.
I have 2 problems to use my keyboard as midi-input device. Maybe you can help me devise a soluction?
1- My keyboard (Yamaha PSR E-413) lack mod-wheel (only pitch bend wheel), so I cannot control the volume in real time. Any ideas? Are there independente mod-wheels? Is there any way to reassign it?
2- I don´t know how to change instruments while playing. The keyboard seems to "connect" allways to channel 1.
Thank you, very much!!!!
