Replacing the keyboard

[P6OB6FOURM]

Has anyone managed to replace the keyboard with a proper one? A TP9S would be ideal (don’t care for polyAT).

The 4 lowest keys on my Fourm always activate aftertouch when pressed. Pretty annoying. And I’m really frustrated with the mini keys too, to the point that I hate using it. So since it needs to be repaired I hope someone else has tried replacing with a proper keyboard and has some good advice to share?

Why can't you request an exchange from the store where you purchased it? Alternatively, I think it would be much better to contact Sequential support directly to get specific instructions and assistance.
I don't think it's been a long time since you purchased it. If the store is unhelpful, you should contact the manufacturer, Sequential.

Thanks but I took it back to the shop last November and all they offered was to send it interstate for repairs that they estimated would take about two months. And they wouldn’t replace it.

Regardless, hoping someone has refitted a full sized 3 octave keyboard and would like to share the details.
Otherwise I may just remove it and strap on some midi keyboard.


By the way. This exam required to post a reply is a real deterrent to participation. So, thanks for any feedback.

The TACTIVE keys are great for conveying subtle nuances in expression; I really like how responsive they are.
I'm not just saying that to be polite.
I also occasionally connect and use a MIDI keyboard with standard-sized keys, and both feel good to play.

I imagine that if I were to disassemble a key and examine its structure, I might figure out how to adjust it—specifically, looking at how the pressure-sensing component makes contact with the key mechanism, and whether there are any variations in that contact from key to key.
Since the issue is limited to the bottom four keys, I wonder if it’s a problem with how that specific key unit is fastened. Most manufacturers use internal assemblies where groups of about four keys are molded together and stacked; I believe the TACTIVE keys likely use a similar stacked structure. I haven't taken them apart myself, but I recall seeing a diagram of the mechanism at some point.
It’s possible that the sensor is positioned too close to the key travel path for that specific block of four keys—though that’s just a guess on my part. That might be what's going on.

Regarding the relationship with the keys:
It is great that you can easily create a shortcut to the setting values ​​for both the amp and filter envelopes simply by holding down their respective buttons, allowing for immediate adjustments. The system is designed to expand the adjustment range when used in conjunction with these settings, which I find very effective.

However, there is one final point I’d like to make: personally, I recommend using the instrument with Aftertouch disabled and Velocity turned off.
Try setting the filter envelope's attack and decay to very low values, using a longer sustain, set the amp envelope's attack and decay to around the 9 o'clock position. Setting the cutoff to around 30%, and the envelope amount to around 30%, among other tweaks.
I think you can get a really wonderful sound, even without velocity or aftertouch.
You can easily achieve a wonderful, nostalgic sound.


I hope your keyboard gets fixed.
and,
The entrance test was certainly painful.
I was previously told that this is done for security reasons.
