Hi all, Looking to purchase an Electro Harmonix B9, C9 or Key 9 to use with a Lap Steel for Organ sounds - What are everyone's experience with them? Good/Bad/tracking Latency issues etc?

well, for organ sounds, rule out the key9, that's more of an electric piano emulator than organs (IIRC it has one organ preset). the B9 and C9 work just about the same except they have a different selection of sounds - check some demos on youtube and see which one has the sounds you like best

They have no latency issues, and minimal tracking issues - I don't remember noticing any bugs with the tracking, at least.
