@ Cimo: Well, as stated in the startpost it will be a 64E. there are 6 channels, and 16 encoders with push button on the right. I plan to have the bottom button on each channel to be a bank select button. This way the 16 encoders are dedicated per channel. That's a lot of tweaking in my opinion;). The pots on the channels will be used for 2 filters and LFO. Probably I won't use send-return because I generally stack all the effects directly in the channels to get some more radical effects. I have: - 42 pots (with 6 faders) - 46 + 16 push buttons ( 6 per channel tot trigger clips and effects) 10 for navigation and menu - 16 encoders - Touchpad (Adesso easycat) I don't know if I'm gonna use all the 6 channels at all time, but this way I could use channels 5 & 6 as effect returns if I feel the need for it. @ Matrigs: Those are Ecler knobs. I got them from Ecler, via a large music store in The Netherlands. At first they couldn't really understand why someone would be needing 70 spare knobs, but eventually they delivered at fair prices (€ ,80 each). Now I am in need of 2 more buttons since my initial design was rather different. Getting those seems to be a lot more difficult... Mayby a small tip for people using the Front panel designer from Schaffer AG: When incorporating artwork such as I've done in my design, take a close look at the drill selection. At standard a ,xx mm engraving tool is used. Since my artwork is 1 mm thick, I've selected the 1 mm drill bit. This brought down the costs for roughly 30%-40% for the artwork.
