Lefty flip is no problem. You just need to re-work your Sys-Ex message so that you assign the correct MIDI notes to each color Rock Band note. So, for example, you need to map the snare drum note to the green button switch, not the red.

Also, don’t forget that you need to double-up on the red, yellow, and blue switches, not the green one (only one green note-snare-in lefty-flip). Sorry if this sounds confusing but the mod is definitely possible with lefty-flip. Good luck.

I played around with using a shorter pulse length a couple months ago. Long story short, I had major problems with anything shorter than 30ms. At 25ms and 15ms, my kit dropped notes very frequently. I wound up back at 40ms, have no dropped notes, and the only time its a problem is on the exact snare roll you are talking about (in Train Kept a Rollin).

If you get a chance, let me know if you notice any dropped notes on simple 8th note beats at 25ms (maybe play through I Think I’m Paranoid or the middle section of Enter Sandman a few times). These are the sort of songs I would notice dropped notes on (i.e. songs that are easy enough that I know its note me missing the notes, it was either the MSA or my kit that was dropping them). Thanks.

I did not experience any additional lag, but even if you do, all you have to do is re-calibrate and you should be good to go.

The 40ms pulse issue has come up before and is actually under some discussion in the rockband.com forum HOWTO thread now. Another user (DorkmasterFlek) has suggested that he gets better results from a 25ms pulse (but that 15ms and 20ms is too short).

I am using 40ms on expert and have not found it to cause any problems so far, but I am probably going to reprogram my MSA-P for a 25ms pulse in the immediate future to test it out.

Do you have any latency with the MIDI controller? Did you have to re-adjust your lag? If so, how many milliseconds did it change?

Also, I saw that you set the switch time to 40milliseconds. I may just be asking a dumb question, but does this prevent you from playing rolls? A lot of hits in the game on expert are much closer to each other than 40 milliseconds. Maybe I am just not understanding that setting.

Thanks in advance!

I don’t personally know anyone, but post this in the rockband.com HOWTO thread and you might find someone nearby.
