https://djdeals.com/ I think these guys have it. I am still trying to decide if I want to spend the big money or just get an EHX 8 step. I ask myself “do I need to run multiply CC messages or not”? I planing on getting a Boss ES-8. The ES will send out tempo sync midi messages controlled by a “wave” (sin, saw, and square… if I remember right). The ES and an 8 step should be pretty powerful. For example I could have a cool filter step patteren with a wave increasing the amount of wet on say a verb. I need to know if I can set up the parameters on the ES wave.
