NAM A2 Raspberry project

this is very cool. Been following quietly. Any thoughts on midi integration? It would seems someone likely to use this, especially a stereo setup, would likely have midi capability.
even just a simple program/preset up down and/or preset follows CC would be cool if there are open pins to utilize.

MIDI is definitely on the list! Probably next week or week after though. The stereo amp thing takes a little more time to finish.

And main focus was that I wanted a nice and user friendly UI, which I believe none of these projects above have (I might sound harsh here a bit, but this criticism is coming from 20+ years of experience in software development - I do this every day with awesome designers). And since A2 is so easy to integrate, why not try to do a project like this?!? Also open sourcing it was very important to me, with easy to get parts, so you don’t have to buy a PCB from some guy on the internet. I’ll just upload the files and you can get a JLCPCB order and job done.

Heard - my other field is working in web UX design/development, so I get the interest in being able to spec your own implementation. Was mentioning the existing software frameworks more as a proof-of-concept starting point than a finished product, or something to borrow from to get going. Interested to see where you take this!

Stereo mode is a huge bonus in what passes for my world. As soon as I can clear out my obligated work queue I'll be all in.

Don’t get me wrong please, but I felt like those projects are not up to the quality I had in mind. Not necessarily talking about the sound of course, but the “packaging” that they are coming in. None of these have a touchscreen, which I wanted to have, since there is so many different ways you can to set the effects.
I liked the PiPedal project, but having a USB interface was something I wanted to avoid.
In mind I had a simple idea: touchscreen, 4 footswitches, master volume encoder, that’s it. Oh and in one enclosure -> no external USB device and that sort of thing.

Oh btw I committed some very important performance updates to the DSP code and tone3000 integration in the desktop app.

I am currently working on dual amp stereo chain setup, very close to finishing it!
I had the first gig with it this weekend and the mono version worked very nicely even in a junky 3D printed enclosure.

Any plans to add compatibility for an expression pedal? I won't look too far into it if it's already on your roadmap.

Actually I haven't thought about it yet, but it is a good idea. Not sure when I'll have free to do it but feel free to share details, what would you do with it?! I am not a huge expression pedal person so any potential use case will help me plan this.

Great progress on the stereo audio side. Let me know what do you think!

UI needs some polishing so this is not the final version, but you’ll get the idea.

Just thinking about digital effects that could be imported: pitch shifters, feedback pedals, rotary simulators, wahs...etc. Having some ability to control those apart from the UI would be cool.

I’m a big fan of mapping an expression pedal as a macro control. Set expression to heel, adjust patch parameters. Move to toe position, then adjust parameters again. Moving the pedal should transition between these two states.

A map to midi with a learn function could be cool. Hook up one of those giant behringer midi foot controllers, load up a wah effect, hit "midi learn" or whatever, tap the wah position "pot" on the unit, wiggle one of the pedals, hit eave, now it's synced.
Or, midi learn with advanced mode.
Complete action as before, but before hitting eave there's another button "advanced" or edit or whatever. Touching it opens a sub menu. this allows you to set the range of the control. I.E. if you tapped "feedback" on you delay "pedal", you can then set the range of which the pot is controlled with said footpedal. If it's a physical button/footswitch, this you set the two values the switch would toggle between.
The sliders could be labeled 1 and 2. when the preset is loaded, it defaults to setting 1.
This could allow sub-presets. one stomp and you boost comes out of bypass, you chorus bypasses and the gain pot goes from noon to 2 o'clock.
Using a simpler controller, like the m-vave chocolate, which is a simple 4 footswitch midi controller, would give you quite a bit of flexibility. 2 switches for preset up and down. 2 more for alternate "scenes" within the same preset.

IDK, an idea. I'm just getting into midi with pedals but the learn functionality has been around in DAWs for decades.
