Updates

new builds for Windows 32/64 bit, mp3 loading fixed]
automated builds on https://github.com/rghvdberg/ninjas2/releases now includes Mac
Mac vst are borked, there's a bug in DPF, will probably be fixed soon
no Linux in automated builds (yet)
Mac vst fixed, automated linux builds added

Hi everyone,

I've made a sample slicer plugin. Consider this to be a pre-release/beta. I'm not really a programmer, I'm self-taught, so be gentle

Ninjas2 "Ninjas Is Not Just Another Slicer"
A Clearly broken™ Sample Slicer
Rewrite of Ninjas, a sample slicer audio plugin. This plugin uses the DPF framework for the creation of audio plugins in lv2 and vst2 formats.

Goal:
Easy to use sample slicer, quick slicing of sample and mapping slices to midi note numbers.

Intended usage:
Primarily targeted at chopping up loops or short ( ≈ 10 - 20 seconds) samples. Think drum loops, vocal chops etc. Currently there's no limit on imported sample length. User can play the slices using midi notes and change the pitch with midi pitchbend.
Features:

Implemented features:

load samples in audio formats as provided by libsndfile
load mp3
highlight slice when midi note is received
maximum of 128 slices
slices 0 to 67 are mapped to midi note 60 to 127
slices 68 to 127 are mapped to midi note 0 to 58
slices can me snapped to onsets
each slice has ADSR
each slice has 4 playmodes :
- single shot forward
- single shot reverse
- loop forward
- loop reverse
pitching of samples (+/- 12 semitones) via midi pitchbend
zoom in/out of waveform with mousewheel
user editable slice start and end points
note: slices can not overlap
dragging the top marker edits both start and end point, keeping the slices continuous
dragging the bottom markers edits the the start or end point of a slice.
programs : store and retrieve up to 16 configurations of slices
normal click restores state
shift click copies current state to new program location
play marker in waveform display
add/remove slices in waveform display : double click within 10 px of slice start/end to add or remove slice

Downloads:
Windows / Mac / Linux:
https://github.com/rghvdberg/ninjas2/releases

Note for Linux:
If the binaries don't work:
Arch users : https://aur.archlinux.org/packages/ninjas2-git/
For other distros :
Build instructions
Dependencies

Code: Select all

    libgl1-mesa-dev
    libx11-dev
    libsndfile1-dev
    libsamplerate0-dev

If you want a standalone jack binary install either libjack-dev or libjack-jackd2-dev

Code: Select all

git clone --recursive https://github.com/rghvdberg/ninjas2.git
cd ninjas2
make

There is no make install, binaries will appear in /path/to/ninjas2/bin/, just copy the binaries to a appropiate location.

I hope some of you might find this a useful tool.

Rob

Binaries for Debian 10 and Ubuntu 18.04 are provided.
For running this plugin you'll need libsamplerate and libsndfile installed.

You might want to note the versions of these libraries that are required, as Linux can be finicky about which version sometimes.

Have you thought about writing an installation shell script that checks for dependencies and installs them if they're not present?

Well ok, for completeness.

Debian 10

libsamplerate0 (0.1.9-2)
libsndfile1 (1.0.28-6)

Ubuntu 18.04

libsamplerate0 (0.1.9-1)
libsndfile1 (1.0.28-4ubuntu0.18.04.1)

In practice, you will probably have these libraries already.
There are still a lot of things I want to add / change to this plugin and packaging isn't really high on my list now. Compiling on linux is very easy but on Windows I have no clue, so the windows version is cross compiled.
Ninjas2 has a good change to be packaged for Arch and Ubuntu Studio 19.10, so that's nice

Nice!! Thank you for supporting Linux!!

Actually I'm a linux user

So maybe it should be "Thank you for supporting Windows"

Little bit of explanation: the framework I use to make plugins recently got an update so that it could use the windows file dialog, so only now I can compile for Windows
Which was a challenge on it's own because I had no clue how cross compiling works. Thankfully I got a lot of support from several (linux) audio devs.

Also: mp3 loading for windows is fixed, gonna update 1st post.

Good one Rob, if you need help for Windows VST2 let me know

Thanks!
The framework conveniently hides (abstracts) all the different plugin API.
Write one codebase, compile vst2,lv2,ladspa,dssi.
In de develop branch of DPF there's also Mac AU plugin support I believe, but I need DPF to support a Mac file dialog first.

Next up is to change the file load in the UI like this

then I'm gonna re-arrange the bottom controls and make room for a pianokeyboard widget.

As you can see, it's all very much in flux, but the basic functionality is here.

There are some videos of people using Ninjas2

ok, back to some bit of coding

I tried the VST2 in Ableton Live Windows 10 x64, but I can play only one note, and Pitch knob jumps from zero to 12, and anyway the pitch doesn't change.

How do you build for Windows from https://github.com/rghvdberg/ninjas2 ?

edit: never mind, I will try to make VS project for it, cloning right now.

Hehe!! Well, in that case, thank you also for supporting Windows!

But being a Linux user, I'm really grateful for the Linux support!

10/10 that will happen

and congratulations, you've just volunteered to be my own personal osx beta tester!

Just wanted to say: finally someone who gives a damn about Mac, but prioritizes Linux

Will give it a try on both systems

I made a free and opensource sample slicer plugin : Ninjas2 [win/linux/mac][vst2/lv2]
