Hi Monster Thank you for a very concise reply. I used midi with the JVM and it was very successful. Had control over reverb, effects loop and all channels and modes. I am hoping the Dsl will allow me the same luxuries. On the JVM I would just set the amp the way I wanted it, go to the midi...
It is seemingly a doddle to program them by USB and you can select PC# & multiple CC#s for each switch.
They are relatively expensive compared to the 91016, and the larger multi-button pedals even more so.
By the time you've reached that level of expense you might as well get a 2nd hand multi-effect.
The HoTone Ampero Control looks like it could be a good bet though.
4 programmable switches in a compact form, and jacks to add more outboard CTL switches.
The Hotone Audio company is highly invested in the development of its employees, is motivated by technological innovation, views excellence in quality as a competitive strength, stands on a foundation of outstanding service, and strives to provide every customer with a sensational experience.
I use a Boss GT-100, which works well, and I get to insert various effects (like a decent reverb!) in a 4CM MIDI setup.
The main limitation of the GT-100 though is the rigid sequence of PC#s.
So, in each 4-preset bank of user patches I have to have all four of the 40CR channel modes.
If I could choose again, I would probably get a Boss MS-3.
Based on a simplified GT-100 effects, but smaller, with two jacks for four outboard CTLs or two EXPs.
A big plus is that you can select PC#s sent for each patch, i.e., 40CR channel modes.
But you lose Amp & Cab Sims, the EXP pedal, Looper, and onboard CTLs.
It also has three FX loops for 4CM and inserting other pedals you might own, but these remain grouped together in the chain.
All programmable with the MS-3 Editor PC app via USB. @FracStrat is your man for more info on the Boss effect switcher lineup.
