I dont have the musical insight that Steve has, but cant you just set PITCH at '1' https://lmms.io/wiki/images/f/fc/General_instrument_controls1.0.0.png and then turn the RANGE-dial 10 semi-tones? sounds horrid, but believe its tuned like you want... i don't understand what it can do for me i use a...

SampleTank 3 it's proprietary sampler.
there are lot of more samplers with better compatibility
in exmaple: linuxsampler, lmms sf2, sforzando

Well perhaps we're talking at cross purposes then... The problem I see is that most synths/samplers etc, i.e. the things that actually produce the sounds, only respond to standard MIDI note numbering. 36 is C and 37 is C#. If you want to use something like 19ET then there are 18 notes between C3 an...

ok.
but i don't think is to hard to implement.
coz its even not some new piano roll - just quantize value by some steps.

and i want to use lmms. i don't like use vst settings - coz its not portable, i can't change simply one intrument to another

ooh im a bit uncertain of what you want Does you want a pitch slide of 10 semitones? yes. but not only 10. in example it needs for doing stuff like that https://en.wikipedia.org/wiki/17_equal_temperament https://en.wikipedia.org/wiki/Quarter_tone#Quarter_tone_scale http://xenharmonic.wikispaces.com...

is there any way for doing this?
in example - i want to quantize pitch value for automatization by 10 steps (irregular or regular step)

how you show this note labels on all pianorolls?

- add multisamples for Audioprocessor or - group many Audioprocessor to one for making possibility playng different samples by velocity or other simple way for creating multisample drums adn other such stuff. i know there is more vst samplers (sforzando, linuxsample and etc.) and sf2 player - but th...

if format will be implemented then there no needs in share libraries - application just add text to clipboard in this format - lmms parse this data and update project - that's it event if this format will be like lmms project file <note pan="0" key="60" vol="100" pos=&q...

no it's not too big samples about 50-100 LinuxSampler vst - is stable and good and i can load bigger sample banks. but i can load succefully only one instance for LinuxSampler vst (1 track). and acctually i use dirfferent types - GIG, SFZ > While a GIG player is coming in lmms 1.2 i know but 1) i do...
