technically the single DSP in the H7600 is exactly the same as one of the 2 available in the H8000FW. So *any* algorithm that can be loaded in an H8000FW single DSP will also load in the H7600. No problems about that! Same power.
What the H8000FW will give you over the H7600 is:
-2 DSPs = double power than H7600 to run 2 algorithms at the same time
-Monolithic Mode = some extralarge presets are only available in the H8000FW as the 2 DSPs can run together as a single one. These presets won't run on an H7600. Most of these guys are surround 5.1 or multichannel presets (6 or 8 channels).
-surround presets (5.1)
-multichannel FX (good for recording and FoH)
-4 analog I/O and tons of digital connections (ADAT and FW) the H7600 doesn't have. It only offers S/Pdif and AES-EBU.
Now, from a guitarist point of view there are many different ways a rig may be assembled and different needs the musician may have. I don't exactly know yours, unfortunately…so I'll try to present some average and extreme scenarios that will show how the 2 units may fit, so that you'll have your decision based on solid ground.
For a professional use the MIDI Virtual Racks available in both units are worth an H-series Eventide. These presets offer 5 highly sophisticated and terrific sounding fx units in each. 10 different tweaks can be created and stored in each. Then you can use a single MIDI CC message to recall any of these tweaks. Please download the Presets Manual for a deep explanation of them, available in the last pages.
The average pro musician may live with these presets, loading one and having all his/her fx already setup and simply change tweaks. If the musician finds the need to often switch between different MIDI VirtRacks presets (as they have different FX configurations) then the H8000FW may have a great advantage as having 2 separate DSPs, it can run 2 complately separated audio paths thru 2 different MVRacks. So one would simply switch audio between the 2 DSPs, especially in a well conceived system with mixer or router. This would kill MIDI latency to a physical 0 time.
The extreme tweaker/looper/experimentalist will find the H8000Fw more attractive as larger presets (monolithic mode) or loops > FX (2 DSPs!!!) are a plus.
The H8000Fw will cover any need at any level…so in time it surely proves its muscles in more different performing and recording situations than the H7600.
If you have a stereo life and the 7600 offers more than enough for you, then there is mo stereo machine that can be compared to it. Both choices will set you on the top.
Last…but not least….the price of the H8000FW is more convenient than the H7600's, considering its power and flexibility.
Lots of deep thinking in your weekend….. hopefully these suggestions show you important criteria for your final choice.
Please ask anything you need to know ahead of time.
all the best
