Those devices should be self-explanatory for those who have been looking for a solution to MIDI TO CV timing issues.
the PDF in the zip gives more info.
I always thought I would buy myself a hardware Midi to CV module (latency free), but after realizing that I would also need pitch modulation and various modules to use with KrOn (mixers and attenuators), the price would be too high (like 300 / 400 euros per oscillator !! ). So I made those to save a lot of money while enjoying more flexibility in latency management.
If you do not use Midi to CV device, or if your eurorack has envelopes and such, or if you use KrOn with Scope devices, you probably do not need those. Otherwise, they are a god send as it eases the process of recording and composing while managing latencies.
Extracts from the PDF:
8-DEL FOR KRON
Adds latency to one or several ADAT Channels to compensate the latency of the Midi to CV signal (if you use the device "Midi to CV").
• In general, you add latency to all channels except PITCH signals: you want to delay the modulations so they match the latency of the PITCH.
• Then you use the VCAs to substract latencie and get it back to zero 'or close to zero, by using your DAW midi channel latency.
A side use is to find new rythmic effect by delaying your modulations (up to 1999.99 ms available), and you can save presets.
The midi is there to control parameters with CCs f you need.
1-2-3-4 VCA
This device is an MIDI envelope generator allowing to shut down the sound of KrOn when you stop your DAW.
In general, you use it;
• on the same midi channel as KrOn,
• OR on a different midi channel playing the same as KrOn but on a different midi latency setting (in your DAW).
• OR standalone without any track latency, to add an envelope to any sound.
In general, this device is used with a latency of Zero, while KrOn is used with a latency of “-xx “ ms (-xx is the negative value of the latency applied to KrOn with the 8-Del device).
It is also possible to simulate latency compensation by adding a little bit of Attack Time to the envelope. This does not create latency but allows to hide a picth latency/portamento effect. This probably depends on the type of sequence you are playing, because you add some attack time that may not be desired, but it is generally acceptable and works fine.
ALL the VCAs variations use the same preset list, as parameters are the same on all devices.
START SETTINGS for KrOn controlling a eurorack modular:
8-Del :
• Delay around 30/40 ms on all channels except the ones carrying a Midi to CV PITCH signal.
• KrOn Midi track in DAW: track latency of -30/-40 ms (the negative value of the delay time set on 8-Del device.
VCA
In the DAW:
• copy the KrOn midi track on a new midi track
• Change the midi channel (eg: midi=CH:2 if KrOn is on CH:1)
• Midi track latency of zero ms (or the negative value of your ulli settings, such as -3ms , -7 ms etc).
WHAT IF YOUR DAW DOES NOT HAVE USER DEFINED LATENCIES ON EACH MIDI CHANNEL ?
• it will be less "in time" because you will not be able to substract latency on the audio signals received from your hardware.
• You may get a similar effect by adding a little bit of ATTACK TIME on the VCAs. It will hide the "portamento/latency" effect from Midi to CV, and in general results are OK.
