I've been using the original Mastermind with a Rack Gizmo for years now for my "Rick Onslow modded" JCM800 2204 amplifier channel/fonction and audio loop switching. The CC88 controls the solo boost on my amp and everything works fine when in the preset mode. Recently, i tried to configure the IA5 to control the CC88 in a momentary mode so when i press IA5 button the solo boost engages and when i release it the solo boost disengages. It's particularly useful in a live situation so you don't have to press a button twice. The problem i have with that is when i return to the preset mode, the CC88 is always off no matter the preset. I'm a little bit confused with this situation and any advise would be appreciated.
