Hey guys!
I tried to do as much of this on my own since I notice sometimes the same questions will get asked multiple times. I've read a ton of them and actually got pretty far with a device that actually works sort of but when this major issue came up I decided to call in a professional. Any help is majorly appreciated!
So what I need is a device that plays 2 tracks, loaded up with samples pulled from the sd card and simply looped (don't worry i'm NOT asking about seamless looping here). Simple controls really, each 'deck' (this is basically like a set of cdj's on a DJ setup with limited controls over the decks so i use the terminology) would have 2 buttons, one for skipping to the next track and one for going to the previous track, then one global button (rather than on each deck this could be a single button controlling both) to 'restart' both tracks playing once i've found the 2 samples i want. Obviously more buttons would be greatly useful and i could do pots, led, all kinds of stuff but just getting minimal stuff going for now. I've gotten most of the buttons in place then something huge came up. it plays the entire first sample once and THEN starts playing the second one. I need them both to start at the same time (exactly the same if possible which up till now i've been ok with a slight delay).
Wouldn't the best solution be to just use a queue where I could get the tracks lined up and THEN play them? Also, this code has it to where when i scroll through the samples i'm actually listening to each one. that's great but at some point i'd like to simply skip to the track i want and THEN just press a 'PLAY' button for both tracks to trigger then. can add a display later to see the tracks but for now i don't mind simply pressing the seek button a couple times by memory. I'm using a teensy 4 with the audio shield for that version and here is my jumbled code.if anyone has any ideas I appreciate your consideration big time this has been quite the discovery process for me!
