H9: Does headroom depend on power supply voltage?


There are several reports on this board of the H9 clipping when used in an effects loop. I'm experiencing this too.

I'm wondering if the headroom depends on the voltage supplied to the H9. I'm running it on 9V, but apparently it works on 12V, too.

Is the input voltage always regulated to the same value or could a higher voltage increase headroom?

H9 Micro Pitch


Hey all,

I recently bought an H9 Max and I love it. But I'm definitely going to be the new guy that asks questions lol...

H9 Step sequencer / tremolo

4 boulevard of broken dreams - green day

H9 Max Never stops offering to download PitchFuzz


My H9 Max may have "everything" but recently when I turn it on, it offers to install a new algorithm: "PitchFuzz".

About 5 times now I've OK'ed the download, and then left the unit alone, but powered up and connected, for hours -- but it does not seem to work.

I have never seen what it looks like when an algorithm is successfully download, thus these newbie questions:

1. Has anyone else successfully downloaded PitchFuzz?

2. I've looked at my algorithms and can't find it.  Would it be showing up as its own icon in the Pitch family of algos?

On the Road with Umphrey's McGee

For almost 20 years now Umphrey’s McGee has been one of the hardest working and most innovative bands in the business. We recently caught up with bass player Ryan Stasik and talked about how the band uses effects with their improvisational style.

Korg A3 Preset?



Does anyone know a Korg A3 or close to it preset on the H9?  Trying to match "Mysterious Ways."  Thanks!  

ram and buffering when switching between presets


Something that puncuates a performance can be when you switch presets,
I'm curious about how much ram is in the h9 and which sort of ram it is etc ?
