Automated echo effects

Please note that this idea is kinda incomplete, but I'm posting it because I think someone could help here :P

Things to think about:

• How to decrease volume? And set detuning? Panning?

Basically, the idea here is for a set of effects (or something similar) that is able to make a channel to replicate commands sent to another channel (or even the same), in a way that makes the task of creating echo much easier, and pretty much removes the need to re-edit all echo channels when you need to change something on the main ("source") channel.

My current idea is to introduce the following effects:

• FBxx selects the channel from where to send the commands to (I'm not sure if this should be in the scope of a chip or the entire song)
• FCxx sets the delay / buffer size for the effects, in ticks.
• FD00 disables the echo, but still leaves the echo buffer to finish "unloading" (see Example 3)
• FD01 disables the echo and clears the echo buffer (see Example 4)

Example 1 (simple)

Assume speed is 4/4.

The selected channel to feed from is channel 1, which is the second one (couting starting from zero).
The specified delay is of 0x0C, or 12 ticks, which in this case is 3 rows.

The previous image is equivalent to:

Example 2 (one channel, and priority over true notes)

Still assuming speed is 4/4.

The echo can be set to occur on the same channel as the notes/commands come from. Really useful for short arps.

Same as:

The echo notes are put in a way that doesn't override the current notes being played (there will only be echo if there's space), like if you were to Paste Mix (Background) the echo notes on the channel.

Example 3 (disabling echo, leaving echo buffer)

FD00 can be used to do this, disabling the echo, but leaving the "set to echo" notes to still echo, until the echo buffer is emptied.

Is the same as:

Example 4 (disabling echo, clearing the buffer)

FD01 is basically the same as FD00, but it interrupts the echo instantly by clearing the echo buffer and sending an OFF command.

(Maybe there could also be other FD commands that send different stop messages, such as FD02 for REL and FD03 for nothing)

Is equivalent to:

Today's updates:

• added example 2 (single-channel echo)
• adjusted the text a little bit so it's more readable (and I had messed up the description of FBxx before)
• added commands FD00 and FD01
• added example 3 (disable echo, keep buffer)
• added example 4 (disable echo, clear buffer)
