I bought my H9 originally for my guitar pedalboard. However recently I’ve been using it for my dawless groovebox setup and it’s great! Maybe an uptapped market for Eventide. I know there are some synth algorithms in the H9 like the Hotsawz. I’d like to see more of these.
Almost all of the various H9 algorithms are great for ‘processing’ a synth signal. But, as you’ve said, there aren’t many that currently ‘generate’ sound [HotSawz, and maybe the old Synthonizer algo]. I’m not privy to any future algos that might be in the pipeline. But I’ll suggest using one of the dozens of FREEZE options currently available as sound generators.
