There is a space missing on the market. Something like the 22500 features and price-point, but with full MIDI Control. Some people need to be able to use these devices in rigs that are geared for recalling presets via MIDI, and then optionally control them over MIDI as well (and some people need clock in addition). The 45000 gets it right, but the 22500 is the device that is more accessible to the guitarist or someone looking for a phrase sampler/one shot trigger rather than a full featured 4-track desktop looping machine. They are very different devices and I think they both deserve MIDI implementations.
