Thanks for the tip Gerald! I'm going to go for 4 2x20 displays, if I can balance my budget on other parts OLEDs might be an option. Designing a front panel with 4 displays is going to be a fun challenge ;) thx and grtz

Hello, I think I found the right display... https://www.displaytech-us.com/20x2-character-lcd-displays-b Will these work without too much trouble? thx and grtz

Thanks to all for the replies! 40x2 displays with an acceptable character size seem to be very hard to find, but I found some 20x2's with characters that are twice the size of the ones on my current sequencer. That would already be a huge step in the right direction. I'll have to look into the subject some more when I have the time to compare specs and datasheets. Peter some of the options you mention sound quite interesting - although personally I'm not a fan of the idea of using a footswitch ;) Perhaps making the main encoders clickable and assigning "step mute" to the click could be interesting? Maybe dedicated encoders for playback mode/direction and clock division/multiplication? From a strictly personal point of view I'd also love dedicated per-step accent and slide buttons or switches... To be honest, the seq V4 appears to be an amazing production tool and I'll be very happy to get one with large enough displays, but I have this silly dream of a seq V5 which is keeping me motivated to learn C ;) You see, I get the impression that most if not all hardware sequencers are either production tools or performance instruments and I want a device that can be both... Imagine a Maq 16/3 with the brain of a seq V4, more or less ;) I'm studying every day so sooner or later that should yield some results... thx and grtz

Hello, I am visually impaired. With optimal correction (glasses) I have only 50% vision in my good eye and 20-25% in the other (so my depth perception is also distorted). My optic nerves are dying and if the medication stops working I will go blind. Not so long ago I was a complete electronics virgin but I have been studying hard to get a better understanding of at least the basics regarding circuitry and components. I'm still very much a noob but I'm slowly starting to see the forest through the trees ;) I now believe that it should be possible to create a UI that is better suited for the visually impaired, perhaps even the blind. After doing a lot of research I think the midibox platform and MIOS would be an excellent place to start from and I already found someone locally who can help with the assembly/soldering. I would very much like to design a front panel with a much larger display - the same 40*2 layout as the "traditional" seq V4 displays (as to avoid any programming cans of worms) but much (much!) larger - but I need to look into how that would affect power draw and find a solution for that problem. Once I have the UI design ready and have a decent enough idea of what components to use I could probably use some help with the design of the pcb and I am willing to pay for that service. Can someone give me an idea of how much it would cost to have a custom pcb designed and are there any people or companies you could recommend? best regards
