We had a small fight about this internally at Source Audio.
When Jesse designed the Hub he thought that 300 parameters was a crazy amount for preset data, so that is what he picked. Then came the C4, which has about 500. At first, the Hub could not save all the C4 parameters. Jesse did a huge update and found a way to squeeze all C4 parameters inside a Hub scene. Then came the Ultrawave with like 1000 parameters. The morphing is the culprit. The only was to save an Ultrawave preset to a Hub scene is by referencing a preset location in the Ultrawave. Its not perfect, but it is still effective.
Connecting to pedals via the Hub is never going to be the exact same experience as connecting via USB. There is way too much data traffic. We have tried to make the experience as good as possible. It is still far better than MIDI programming. Some others might want to comment on this.
