While traditional Voigt pipes have a certain 'bouncy' charm, if you look at BB's sim of one Vs a more refined version, I believe you'll prefer the latter.

Anyway, download the demo, worksheets, MJK's extensive/informative docs and ask Qs as you go. Me, BB, and a few others have got you covered so MJK can continue delving into horn theory to improve his worksheets. The GW has a bit high Qt for a ML-TQWT (ML-TL), but is fine for a TL, TQWT, or end loaded Alpha TL. For Rick's Alpha TL, I posted a little Excel spreadsheet that you can transfer the calc'd info to Mathcad to make a plot.
