Hey all…
I’ve just started doing some “serious” work with MG2 and have run into a couple of problems that there may be some way to overcome. It could be that my instrument isn’t well suited to MG2, but I have two of them, and I’m running into different issues with each.
My instrument is a Chapman Stick. I think that MG2 is an ideal solution for Stick players as hexaphonic pickups are a) expensive b) difficult to install and c) becoming increasingly rare. To be fair, I’m extremely impressed with how well MG2 works! Just amazing. But as to the problems, read on.
I have two instruments, let’s call them Mr. Brown and Mr. Blue just to keep them straight. They have slightly different tunings which may be the cause of the different behavior I’m getting from the two instruments. Mr. Brown is tuned in Baritone Melody. Mr. Blue is tuned in Matched Reciprocal. What this means is that the 5 “melody” strings (the output of which is being run through MG2) on Mr. Blue is tuned 3 semitones higher than Mr. Brown. The strings on both are tuned in ascending 4ths just like a guitar (without that major 3rd we’re used to seeing at the “B” string). Mr. Brown is thus tuned on the “open” strings to C#(2), F#, B, E, A. Mr. Blue is tuned on the “open” strings to E(2), A, D, G, C. Thus as you can see, not significantly different than standard or drop-D tuning on a guitar. Note that I put “open” in quotes like that because on a Stick (not sure if this is true on a Warr guitar) the open strings are never played. It’s a “touch” or “tapping” instrument, basically using hammer-ons to sound the note. The lowest possible note that is playable is a semi-tone above the stated “open” string tuning, as you can’t “tap” the string against the nut. Something else to be aware of (and that could be contributing to the problem) is that the strings are (when compared to guitars) longer, having a scale length of 34"
On Mr. Brown, everything is working superbly until I get to the 5th string. It seems that MG2 can’t track the fundamental of most notes on that string, anywhere along the fretboard. It often tracks as a semi-tone low, or, particularly on a held note, will “stutter” between the note and an octave low.
On Mr. Blue, everything is working really well, including everything on the 5th string. However, on that instrument, MG2 is interpreting the attack as progressively softer as I move to higher strings, until I get to the 1st (highest) string, where at first I thought it wasn’t working at all, then realized I could either crank the volume on the amp, or hit those frets really, REALLY hard, to sound the note.
On both cases, I adjusted the “open” string tuning in MG2 for each. I didn’t know what to do with the 6th string, so I spec’d it as what it would be if I was playing a 12-string instrument (6 bass, 6 melody) but beyond that I’m at a loss as to what tweak I might be able to do to get this working across all strings.
If it makes any difference, I’m running MG2 within AUM on an iPad Air 4th gen. Input to the iPad is through a Focusrite Scarlett 2i4 USB audio interface.
Thanks for any suggestions!
