The plot thickens though! Gumtown has posted another account of a different account!
Here is another account of the GM-800 posted and observed by myself on VGuitarForums, so it must be true then.
You can post an account of an observer, observing himself posting an account of real life experience with the GM-800 . . . right ?
So you should trust me when I say the GM-800 is good !! because I have actually tried it myself and it works (after a setup of basic system functions)
Certainly much better than the GR-55.
As for HRM processing devices like the VG-88, VG-99, SY-1000, and not having the best guitar to midi speed,
the guitar to midi is not the core function of those units,
where, as far as the Roland dedicated PCM synth units go, guitar to midi is the core function,
so of course those units will do that function better.
I have no desire for the GK-5 pickup as I already have many instruments fitted with the legacy 13 pin pickups, and the GK-5 does not offer GK-Vol or S1/S2 switching.
I am sure in the near future Boss will release a function featured GK Serial pickup.
I have already loaded in a few Expansion packs (PCM Samples) and Sound Packs (synth voice expansion), but to get the most of the available,
you can do just a 3 month $30 Zen Core Pro subscription, download all the Expansion and Sound packs, design few new voices in the Zen Core Pro editor (Zen Core has the synth hardware of all historic Analog and digital synths).
Then only need to subscribe temporarily the the Zen Core only if required, but I really can't be bothered wasting my life trying to make new sounds, I would rather load in what I like for the Sound Pack sets, and get on with it and play.
I am really liking the GM-800,
the note tracking is solid,
and the basic elements of the instrument tone set are better than the GR-55,
in a way that you can choose clean tones without the added effect and modulations the GR-55 instrument tones have burnt into the PCM sample.
This allows you to add modulations and effects to basic tones only when required.
The adjustable dynamics and velocity settings per tone is very useful to sculpture great reactive dynamic to your tones.
Some of the boutique chorus/delays are great !! they add a full spread to the sound, and finally a pitch-shifter effect to add harmonies to a single note.
I am loving the feature of being able to play tones from two sources, GK and midi in,
but my only feature wish for a firmware update is to be able to select the "Source input" options "per patch".
Maybe an Arpeggiator (sequencer?) would have been a handy option too.
It can be easy to get overwhelmed with option-overload, but when creating a new Scene, start with everything 'off' then just add (and work with) one element at a time.
