these effects may share the same effect memory: (0,) 1, 2, 3, Q, R
Qxy and Rxy may only use the high nybble for effect memory
Trigger mode must be used by global control effects: B, C, D, F, O
Switch mode may never be used if all parameters perform one-time action: 0(if resetting counter), E(length counter), H(2A03), I(2A03), L, S, Z
Switch mode may never be used for effects involving delay because the duration may exceed that of a single row: G, L, M, S, T
Trigger mode should be avoided if there is an initial parameter that may be non-default: E(mode), H(FDS), J(5B), V, W, Y(N163)
Eligible: 0, 1, 2, 3, 4, 7, A, H(5B), I(5B), I(FDS), J(FDS), P, X
