There are lots of posts asking about full midi transition etc. and Wav player enhancement for backing. I think a product niche not addressed is a standalone single instrument WAV player that is tightly integrated with a non-computer sequencer (BB). Some failings of loopers are that songs and patterns are not integrated with the sequencer playlists so more computer work and less play time, also more than one loop playing from a single audio out make mixing difficult. Full sequencers like Ableton with an APC are infinitely flexible but are designed for artists with at least one free hand. Drum boxes with Midi only like the SR18 etc. don’t have great sounding bass lines or wav support and the big negative to live use of most multiple instrument playback devices is also a single out to the mixer. Multiple vendor song management and live control is currently like having a band conductor trying to not only let band members know when to start/stop/slow down/get louder but also trying to run around and turn all their music pages to keep them playing the right parts of the song or having some players that only can play one or two patterns over and over and who wait to each be tapped on the head to know when make the changes.
So… dear Santa, Once the paint is dry on BBv1 please consider making a standalone single channel wav loop player that uses the BBM to load/manage patterns, wav samples etc. with an enhancement to BB that supports midi transitions so that BBM is the single source of playlist management. A separate WAV pedal is needed for dedicated output to the mixer with only a master vol and mute foot switch, could even be a volume pedal layout to make it able to be muted and tweaked live.
A MidiBuddy could be a similar minimalist pedal, that would be controlled by the BB as the master sequencer, song tempo, stop, pattern select etc. The midi buddy would also differ from BB in that it would output notes and other midi to sound modules and it would be a sound bank for one instrument at a time setup per BBM with dedicated audio out.
A tempo up/down by one BPM per push option via midi expansion or as a BB setting option in the pedal configuration would also be a nice feature for a live running song to avoid tap tempo trainwreck adjustments also.
There are plenty of loopers and plenty of and computer software for making beats. I’d not want to see BB expanded to attempt to concurrently play WAVs or other midi channels because it would limit CPU/RAM options for songs and also would be limited by its’ physical controls to try to control a more full band lineup.
