There are few NDS flashcards that have up-to-date firmware and kernels (that is, can be played in the latest systems AND play all the latest games). Aside from the evr-popular DSTWO, R4i Gold (and a few other R4s), there are not many left. The M3i0 (M3i Zero) is one that has an official update to be able to be started in the latest DS systems but has a 3rd-party firmware that works, albeit a rather recent one. (Only the GMP-Z003 is the one that actually works in both areas, though...)

M3I Technologies - Laser Pitch to MIDI Pitch Detection 2.0 The patent-protected LPD™ (Laser Pitch Detection) is an exciting new state of the art, breakthrough technology pitch detection system, which is able to sense the pitch of a forthcoming tone before a string is plucked by a finger or a pick. The maximum length of a guitar string, between the bridge and the nut, determines its deepest note. By shortening the string with a finger or another object along the fingerboard, higher notes are generated. The LPD™ system measures in real-time, precisely the distance between the bridge and the shortening object. It uses this information to calculate the frequency of the note that will be played.
