endobj I've done a similar thing on my MPK using layers of electrical tape and, while finicky, it did make a huge improvement. And I just did it on the LP Pro and it's fantastic! Are you an Audio Software or Plug-in Developer? The different off to on pressure idea is interesting but Im not sure if it might fall down on the same physical limitation. Hysteresis is the word of the The text was updated successfully, but these errors were encountered: Okay this is interesting. I'm losin' faith Maybe there is some reluctance to this idea at a marketing level or something? Hey no more feedback from DVHDR? <, Wow! 11 0 obj I was holding on for a proper response from someone in the know. Like to the point where blowing on the instrument would trigger the pad, or modify the aftertouch, if that's even possible :). endobj Recently I've been playing with my LPP again and I'm having issues with soft notes dropping off after the initial attack. The reason I bought this thing was because I enjoy playing the ableton push more than a lot of keyboards, and thought this might be similar, but at the current minimum threshold the pads are like nice MPC pads. It was fast and easy. %PDF-1.7 I have bought a launchpad pro today but have to return it. It'd be so wonderful to have that ADC function! <> Thanks for that one! Interested to hear if anyone else attempts this mod.

<> I've nearly stripped the screws for my MPK from dismantling it so many times, trying to fine-tune the number of layers of tape under the pads so they're as sensitive as possible without sticking or mis-firing. privacy statement. We didnt go this route although we did spend quite a bit of R&D time looking at it. Luckily I moved on to a Maschine Mk2, which is the benchmark for drum controllers in my opinion. I have no issues at all. Getting Started (AKA What is the best? You may need to open up the unit a couple of times to deal with crosstalk, etc. Already on GitHub? 5 0 obj Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I guess projects like https://github.com/jrcurtis/subsequencely could then easily make use of it and implement their own velocity readout algorithms. So just to sum this up: There will no changes regarding the stock firmware in terms of sensitivity, but you will try to expose the threshold value within the API to allow it to be changed for projects built on top of the open source firmware, right? I might revisit that and make it work for each pad individually to compensate for any variation across pads. Hold unit together (side and front panel), and flip it over. We designed it as a percussive instrument in that you do need to at least tap the pads to trigger them. endobj Reply to this email directly, view it on GitHub I feel like it should have been designed like this in the first place, but it seems pretty common for pad controllers to have a gap between pads and sensors so maybe manufacturers have their reasons. <> I expect the cones will also have some interesting effects on the optics. The Launchpad Pro feels like a higher quality instrument now, and I can play it much more lightly. notifications@github.com> wrote: @dvhdr https://github.com/dvhdr @whibble https://github.com/whibble A lot of people voided their warranties trying to squeeze a bit extra sensitivity out of their pads, myself included. Also, the 8x8 grid makes the Launchpad Pro more suited to playing harmonic instruments, which implies multiple fingers playing different notes at the same time. Since the pressure applied from the arm is divided over fingers, playing one or two pads per hand is doable (although still clunky), but each additional note becomes more and more difficult. To achieve this the mechanical construction would have to be different with every pad in a permanent on state and the threshold controlled entirely in firmware. In that case it would be great if you could provide any feedback on where to start. On Mon, Aug 15, 2016 at 11:49 AM, Fabian-Robert Stter < Of course that's more computationally intensive than a moving average, but being able to experiment within the capabilities of the hardware would be very rewarding I think. Can't speak for the Pro Mk3, I only own the Launchpad X. <> I think it really is a big issue, and im sure we are not the only ones I'll jump back in and re-express my interest in this being resolved/improved. workaround) to finally purchase the LP Pro, respectively one for each of I suggest to work around it by release a accessory pad cover like this: Only 4 buttons are shown in the pic, and the cones need not to be that sharp, but you get the gist. endobj Of course, I have no idea what your code looks like internally, or how the low level "closed firmware" is separated out from the "open firmware" part. This was marketed as something different. @whibble @dvhdr Apply Avery stickers to the bottom of each pad (see notes on sensitivity / how many to use below). There's a few stuck pads when I first power it on, but I run the auto-calibration in my custom firmware and it sets the low threshold just slightly above the noise floor. Micah, @jorgen1005 the sensor data is exposed in the API now, but there's an aliasing issue which prevents having a very low threshold (which was the whole point of exposing the raw sensor data in the first place), So, looks like the alias issue-thread is dead. It tires my fingers too quickly. Given the initial marketing of the Launchpad Pro as a "pro performance instrument", and the recent marking of the Launchpad Pro as "a hackers dream", those expectations were and still are reasonable. There is a table for each of the velocity curves and this acts on the values read to become the final velocity output. Hope to hear some good news soon! Sometimes I still get some ghosting from the plastic case flexing, so I can manually bump up the trigger threshold a little bit to eliminate that. The new scales update is great. Hello there, whatever its worth to the product owner, I and a friend have been using the LP Pro for days and we both also experienced this problem. I'm a serious keyboard player, and would love to On a keyboard you have the travel of the key whereas on the Launchpad Pro, the pads deflect slightly but remain basically static, of course.

Hey thanks for being receptive. This thing is sitting around waiting, collecting dust. After a while of bashing away a bit harder than I'd like (plus a little extra so I don't have dead notes) I end up with stiff hands and sore knuckles. I used to have to push my fingers perpendicular to the pads and use arm/wrist to get to full velocity. (Another being poly AT, that's why I got a LP Pro instead of a Push) I think many other people are the same, look at MPCStuff and their pad corx and fat pads. Maybe instead of averaging the ADC signal and comparing it to the threshold, we could use something like a transient detector where the signal feeds two envelopes with slightly different attack times, and the slower one is subtracted from the other to get a signal based on rate of change instead of only magnitude. Such a shame :(. I've always thought about doing it with the LPP but didn't want to be the guinea pig. <> The Kensington lock metal piece may fall out, you can put it back later. If I slowly press on a pad, I can find a narrow range of pressures the pad flickers on and off with very little change in pressure. ), Samplers, Sampling & Sample Libraries, Computer Setup and System Configuration, Sell & Buy (+Special Offers, Deals & Promos), Was $249.00; Save $200.00 until 01 Sep 2022, Blue Cat Audio releases Blue Cats Remote Control 3.1 - Virtual Control Surface Software, VG Trumpet releases "VG Trumpet Harmon muted" for Kontakt with Intro Offer, accSone releases "quick-start" crusher-X 9.52 update, Black Octopus Sound releases Deep Trance - Samples, MIDI Files, and Serum Presets, Patchbanks releases Mogami Percussion SFX, DroneLab soundscape synth for iPad/iPhone updated to v1.3 - adds sound randomization, visual enhancements, and more, Soundiron release Cosmic Hand Pans for Kontakt Player & NKS, Zenhiser releases "Prism - Psytrance" Sample Pack, Samples From Mars releases "Vinyl Drums" - drum sample pack, Studio Major7th updates SSG7 V to v1.3.0 for Windows.

Once the pad sheet is back on the fsr sheet, you can lift each corner to make sure the fsr sensors underneath are aligned, and nudge the fsr sheet if needed. With an FSR you read the change in pressure over a fixed period of time very early on after a change is detected. Hey @Kyran-C - fair point, the Circuit stuff has been a big deal for me. <> As it stands now, the ADC readings are usually a bit jittery with really light touch, but consistent with more firm presses. There is only a limitation, that a chord must not be a square. Right now, the controller feels tuned like a drum machine. x{VanJI !DEj@muZuUZqzoo:uffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff Thanks as always! If the issue here is a hardware issue (too much noise at lower pressures), one thing that could help is to make the 'pad off' minimum pressure lower than the 'pad on' minimum. If we were to do this mod to effectively have the pads always slightly pressing against the sensors, you'd push past the noise floor of the ADC so that any slight pressure would register with decent strength. This is a hack I've performed successfully on just about every pad controller I've owned (albeit not with 3-ring binder stickers, but same general principle). Your only option is to use the weaker muscles in your hand. This change is not continuous so, in firmware, there is an associated low limit that is fixed to correspond to when the voltage has changed enough to definitely be a pad press. Though it's been fun getting back into this with the flash storage stuff, I hope to make more time in future - but all that is just good intentions at the moment! @Kyran-C, Hey glad to see another fan of the tape hack! Perhaps tolerance issues with the pad molds, or extra work to assemble or calibrate them? If I wanted drum pads, I coulda bought a Maschine or something from AKAI. i have not yet installed custom firmware on my launchpad but this will make me take the plunge. If it didn't work out well then at least you all gave your users a chance to see what they could do! It's attached to the small USB board via a surface-mounted pin connector which can be a bit of a pain to align and snap back together. @svankov Thanks for the info. You can slide your finger nails between the back and side panels to lift the back off. No update in half a year.

3 and 4 feel incredible, but were causing some crosstalk and pads getting stuck on. I couldn't get anything out of the sensors that looked like to be some starting point for some smart algorithm that could detect the pad hit from noise. In the open source firmware, is there a way to adjust with the minimum pressure threshold for triggering pads off and on? The original firmware engineer has moved on, and the rest of the team are busy working on new things. We've made some improvements to the ADC noise and crosstalk. endobj by KVRMember2022 Mon Jun 27, 2022 4:09 pm, Post Some randomly triggered pads that loosening their nearby screw(s) resolved. In summary, there is a hard-coded threshold that it may be possible to expose to play with (and we can look into that subject to demand) but I expect that changing it wont make enough of the difference you are looking for. I guess I will have to go with the Linnstrument! been using the LP Pro for days and we both also experienced this problem. endobj There is a low setting for this and it may be possible to fiddle with it but it will not give you the hyper sensitivity you may be looking for. I know a lot of this is physical limitations of the sensors and pad architecture, but any access you can open up to the low level software side would enable people to tinker and perfect it to their liking. This leads me to believe that the sensors are pretty accurate near the current minimum settings, and that some software changes could make me very happy with the controller. <> this issue again. For example, sometimes I will play a chord with my thumb, pointer and middle fingers and the melody with the ring and pinky. I had some stuck pads which were mitigated by loosening the center screw slightly.
