I have a Kawai vpc1 which appears to have an issue when using the sustain pedal with Pianoteq. Occasionally the sustain pedal when fully depressed is showing as up on the Pianoteq interface. This isn’t happening often but is very annoying when it does. I am using the F30 pedal unit which I’m aware has some issues. I am trying to get it replaced under warranty by kawai. If anyone does have a kawai VPC1 can you use a Single sustain pedal with a polarity switch instead of the provided F30 unit that it comes with. Are there any adjustments I can make to the pianoteq pedal settings to help with this issue. Many thanks

well the original f30  pedal made by fatar is terrible . I had at least 3 faulty units . This is why Kawai  engineered their own  pedals , F10H ( single pedal) and RFP3 ( triple) with optical sensors which are the best by far of any other pedals available . Now coming back to your problem , the cheapest solution is to keep the F30 for Una corda and  sustenuto , buy  a Roland DP10 , there is a switch  that configure the pedal either as on/off switch or continuous , use conitinuous , and change the polarity ( is inverted compared to the original VPC1 pedal) using the tick box ✅ option in pianoteq , by right clicking on the pedal . The Roland pedal is ok’, its a bit noisy in terms of of midi , as it doesn’t filter values when you fully depress the pedal and send a lot of values close to 127 as soon as your foot pressure varies a little bit ) the best technical option is to buy an audiofront midi expression Quattro pedal interface and buy 3 or 4 Kawai F10H optical pedals . They last forever are extremely sturdy and extremely smooth and precise . Now they need power(3.3V )  to work. The audiofront  accepts these pedals and power them . Having 4 pedals is great with pianoteq as you can have the standard 3 grand piano pedals + thunder , sordino, , harmonic , Mozart rail etc …
