Hello everyone,
I'm using John Melas software to edit my own waveform on the expansion flash module in order tu use MOXF as a sampler.
I've read on this site that the keybank is a sample with the information of root note and range but I can't really get how multiple keybanks can create a waveform.
In the John Melas's software I can load a sample, set the root and the range and, for me, that's a waveform that I can load on the flash and, on the MOXF, I can use as an element of a voice (indeed I prefer to leave the full range of the keyboard on the software and then, once it's loaded on the MOXF, set the range on the screen "osc ->limit";)
So, that's, for me is a waveform, not a keybank.
What's exactly a keybank then?
Thank you,
Luigi.

No, a sample once given a root note, a key range, a velocity range and a play direction (one shot, loop, reverse) is called a Keybank.

There can be 256 Keybanks in a Waveform. Let’s talk about creating a piano like the S700 it is made from three Waveforms.

A soft strike Waveform
A medium strike Waveform
And a hard strike Waveform

Each Waveform is made from 90 samples, and is a set of samples that stretch across the range of the piano
That’s 90 Keybanks per layer.

Approximately every other note is sampled. There are left samples paired with right samples... a maximum of two samples can occupy a Keybank... this accommodates STEREO (a left and right).

A maximum of two samples can occupy the same Key Range and Velocity Range.

So at maximum you could map 128 stereo samples in a Waveform. 2 per Key across all 128 notes of the MIDI keyboard (C-2 thru G8)... well no one needs all 128 notes... a piano goes from A-1 through C7.
Don’t let the theoretical maximums confuse you, most instruments concentrate the samples where they are necessary when creating an instrument sound. More are typically used in critical areas of the instrument.

Samples can be stacked vertically (Velocity). For example, a drum kit Voice: when recreating a Snare you may encounter 5 samples stacked vertically each mapped to sound at a specific velocity range. Each Key in a drum kit Voice has a Waveform... it could be made from samples mapped at different velocities. Again a maximum of two samples can share a Keybank (to accommodate Stereo). Each velocity 1-127, could have Keybank...containing a maximum of two samples.

No one would build drum kit like that because you don’t NEED samples that differentiate velocity of 1 from a velocity of 2, or 40 from 41 for that matter... I bet you were unaware that most snares and hihats have 4 or 5 different velocity swaps to them... the theoretical idea that a different sample at each velocity sounds good on paper, but is hardly worth the work assembling it. The ear/brain does not need 127 velocity layers to fool it..

A total maximum of 8192 Keybanks can exist.
A total of 2048 Waveforms

Thank you very much.
Now I will refer to John Melas software manual to understand how to join multiple keybank into a single waveform.
I hope it will be easy.
Thanks a lot
