Topic: Bad experiences with the Kawai VPC1. Looking for alternatives.
Hi everyone! First post here.
Pre-post edit: Oh boy, this has become a wall of text. Jump to the TL;DR if you're not willing to read through all of this.
About 7 Months ago, I upgraded from my trusty Kawai ES8 (RH3 is a nice keybed overall, but very light and annoyingly noisy) to a new Kawai VPC1.
So, here's my setup: The VPC1 feeds MIDI into Pianoteq 8, which outputs the audio through a Steinberg UR22C interface into Focal Alpha EVO 65 studio monitors. I even 3D-printed some custom brackets for the UR22C and my HP mini-PC to mount them to my K&M Omega 18810 stand. To me, that's a pretty decked out setup, at least for my purposes as a hobby pianist mostly focusing on classical music.
Everything could (and should) have been so great: I much prefer the highly customizable sound of PTQ to the engine in the ES8. The monitors do a great job and provide more than enough volume. And - most importantly - the VPC1's RM3-Grand II keybed feels very good, substantially better than the RH3.
But, sadly, my experience regarding the QC with the VPC1 is not very good.
The first issue
I quickly noticed that I had some obvious "hot" keys which delivered a drastically higher MIDI velocity than their direct neighbors. It was bad enough to really bother me, especially when the same few notes clearly stuck out in fast arpeggios. In my search for a possible fix, I came accross this thread which suggests that this was not an isolated case: https://forum.modartt.com/viewtopic.php?id=6886
At first, I simply measured the response of all my keys and calculated individual offsets to correct the issue using the VPCEditor. This helped, but now I couldn't reach high velocities on the keys with larger offsets anymore.
So, I contacted my dealer (Thomann.de) and arranged for the unit to be picked up and repaired. Almost four weeks went by before it finally arrived at my doorstep again. I went to test it and... I was pleasantly surprised seeing that my velocity issues were mostly resolved, I could now cover the full velocity range 0-127 on all keys and the response (while still not perfect) was much more even.
The second issue
Everything was good for the past three months. I really enjoyed playing on the VPC1. Until a few days ago, when all of a sudden the E1 key stopped working. Nothing happens when I press it. The only way to get it to sound is to fully press it down, let go just a little and then fully press it again. I suspect sensor 1 has died while sensors 2 and 3 still function.
Since E1 is on the far end of the keybed, it doesn't bother me during regular playing all that much. But still, this means I will have to once again contact my dealer and arrange for a pickup, leaving me without a piano for likely another month. I also have to carry the VPC1 down from the second floor, which is not so easy considering the weight.
TL;DR:
In the seven months that I've owned a (new!) VPC1, I now have to send it in for repairs for the second time due to keybed defects.
I'm really getting frustrated, and I'm entertaining the idea of selling the VPC1 once it has been repaired since I just can't trust it anymore. I've always planned that my next piano will be a decent acoustic upright (preferably with a silent-feature) and that the VPC1 could fullfill all my needs until then.
I'm not quite sure if I want to invest that kind of money (north of 9000 €) into something like the K300 ATX4 or Aures 2 just yet. I'm also not convinced that I want another digital in the slab form factor, as I'll have to move my piano setup into the living room at some point in the next 12-15 months, since we're planning to have kids and will need the room it's currently in. And my (soon-to-be) wife and I agree that we want an upright/console-style piano in the living room for the looks. No studio monitors or any other clutter.
Looking for alternatives
I guess I'll look into the current higher end console-style digitals (CLP785, CA901, LX708, GP510). These are all within a pice range of 3700€ (CA901) to 4600€ (CLP785) in germany, about half the price (or less) of a K300 ATX4. Does anyone mind sharing their experience with any of these models and how well they play with Pianoteq through their integrated speakers?
And does anyone know if the latest Kawai GF3 keybed has similar issues?
I'm really sorry for the sheer wall of text above, I just had to write it off my chest
