I'm having a certain problem with G-Stomper Studio.
The symptom is that when playing a chord with a primitive waveform (e.g. sine wave) applied to the synthesizer section's filter with an LPF (cutoff of about 40%), a clicking noise occurs when the keys are pressed.
By applying the FX INS LPF without using the synthesizer's LPF, the symptoms can be alleviated, but it is not a fundamental solution.
Is this a bug? Or is it a specification?
We ask the developers to come up with a fundamental solution.

Re: Clicking noise occurs when typing on the keyboard
Welcome to the forum, tsukushi_4649
and thanks for your message.
This is not a bug. You can get around it by changing a setting.
You hear a click when using a short attack phase in the amp envelope while playing a sound with very low harmonics (either a sine wave or any other waveform going through a low pass filter).
The reason why this happens is that the LFOs and envelopes run by default at 1/16 of the audio sample rate.
Means if the audio sample rate is set to 48000Hz, then the LFOs and envelopes run by default at 3000Hz.
This is, as you might expect, for performance reasons.
For real time use, especially, in the mix, this is in most situations not significant. But like in your example with a filtered wave and a short attack, you can hear it.
My recommendation is to stick with 1/16 for real-time usage, and set "Highest (at sample rate)" when you export a track or loop as audio.
With the "Highest (at sample rate)" setting, you won't hear a click. But it'll be very hard on the CPU, as there are a lot of envelopes and LFOs running.
However, you can experiment with the setting:
Main Screen / SETUP / AUD / Overall LFO/Envelope Accuracy
Possible values:
