Nils‘ K1v: Demo Video by MOSS

Just in case you didn’t see it yet, I am so excited about what Jürgen Moßgraber aka MOSS did. He created a whole song with the K1v. Except for some FX, there are only K1v instances in his music track. When listening to it, it instantly reminds me of the 80s. Thank you very much Jürgen for doing this! 👍😊

Nils‘ K1v updated to version 1.04

Nils‘ K1v has been updated to version 1.04, which brings the following improvements & fixes:

  • [Accuracy] LFO behaviour didn’t completely match hardware behaviour, especially for higher speed values
  • [IMP] Window size is remembered when the plugin editor is closed and reopened
  • [FIX] In Solo mode, audio clicks were audible when playing a note while another one was still playing
  • [FIX] Audio processing could lead to clicks/pops in some hosts. I personally
    didn’t experience this so feedback & if possible a recording of the issue would
    help. Thanks 😊

Nils‘ K1v updated to version 1.03 + BIG THANKS

I am sitting here and I’m overwhelmed by the amount of positive feedback that I have received today. 😊 I didn’t expect that so many people are still interested in such an old 8 bit machine.

Thanks to everyone that contacted me to raise issues, improvements and to all donators, absolutely love all your support! ❤

I updated Nils‘ K1v to version 1.03, which brings the following fixes & improvements:

  • [IMP] SysEx Parameter Changes are now fully supported
    • They are sent, which allows the plugin to edit a real hardware in realtime
    • They are recognized, which allows the plugin to be edited via external/existing editors
  • [FIX] UI crashed on second opening after using the Source Mix Joystick
  • [FIX] Reaper specific: Keyboard Shortcuts 1,2,3,4, E and C intercepted entering text to input fields (search box in Play Mode, preset name in Edit Mode)
  • [FIX] In Solo Mode, releasing a note always stopped all voices if the note being released was not the one being audible
  • [FIX] Midi control changes Hold Pedal & All Notes Off didn’t work
  • [FIX] UI did not update if the current preset was changed via Midi Program Change

Kawai K1: VSTi released!

During past weeks, I worked a lot on the User Interface. For faster iteration times, I did the layout in Unity3D and wrote an exporter to create an xml and bitmaps for VSTGUI. This allowed me to do adjustments to the layout very quickly:

The first layouts that I posted some time ago had to get some updates. I forgot a section to set the name of a Preset and the Play mode page had to get some additional buttons, plus a search box to find presets quickly.

Some people pointed out that it would be better to have all sources on one page for faster editing. I tried it, but it just didn’t fit on one page properly. I didn’t want to ruin the design completely and the editing functionality is already really good in my opinion.

For the emulation engine, I had to do some minor finishing touches and fixed some bugs:

  • Ring Modulation didn’t behave correctly when being set to reverse mode
  • Fixed ring modulation caused envelopes to be applied twice, resulting in wrong decay & release behaviour
  • Implementation of Poly 2, Poly 1 and Mono modes was still missing
  • K1v will now correctly respond to Sysex messages, just as a real K1 does
  • Support to mix Source levels with the Joystick
  • Some code fixes to support 64 bit compilation
  • Midi: Pan, Main Volume, Program Change including Bank Select, Hold Pedal, All Notes Off
  • State serialization to make it possible that the state is saved as part of a DAW project
  • Wrong key scaling curve 4

And lots of other smaller things! 👍

Kawai K1: VST features, differences & UI mockups

I’ve got many questions about the VST plugin, so I wanted to give some more & updated information about it.

VST Version & Operating System Support
  • Initial plugin will be a VST 2.4 plugin (VST3 later)
  • Two versions will be available from start, x86 and x64
  • As I don’t own a Mac and I’m not familiar with Mac programming, I can’t port it easily to a Mac AU. I have a colleague that could help out here, don’t expect it too soon though.
Features
  • Instead of the original voice limit of 8/16 voices, the plugin will have unlimited voices
  • It will contain the K1 factory bank, the K1-II factory bank and all ROM cards, giving a total of 768 Single presets. Multi support is not planned for the first version.
  • Full editing capability (see UI section below)
  • SysEx import & export, which will basically make the plugin become a possible editor for a real K1
  • All Single parameters can be VST automated + the Source Mix Stick will get two automatable parameters
MIDI

The plugin will support all MIDI messages that the real K1 supports such as program changes, Midi CCs, receiving Sysex is supported as well:

  • All Data Block Dump (i.e. a full Bank of Singles)
  • Single Data Dump (one Single)

I extended the MIDI feature list compared to a real K1 to now include support for the following additional midi messages:

  • MIDI CC 10 (Panning, which the K1 did not support)
  • The K1 Source Mix stick will be mapped to two Midi CCs
  • Bank Select – Used to switch between the various factory banks and ROM cards. As usual, Bank Select must be send before a Program Change
  • Pitch Bend wheel will use full precision (K1 is limited to 8 bits)
  • Most of the Single parameters will be mapped to Midi CCs so they can be edited via an external Midi Controller
UI Mockups

I’ve received a lot of feedback for the very first UI mockup, which wasn’t even finished. I continued working on it to clarify some things. My intention was to have something that someone instantly recognized as being a K1. But of course, at the same time I always wanted the UI to be functional, including full editing capability.

Below are the two editing pages (Common + Source) and the „Play Mode“, where you can browse through the banks / singles.

Hope this clears things up a bit 🙂 And yes, the VST window will be resize-able, maximum resolution is 2560 x 1440
