Colab Notebook as online step-by-step tutorial doing all the work – no need to install Python
Want to have a Hacktribe, but don’t want to install Python? You can use this Notebook – which you can run on a virtual Python environment provided by Google, called Colab. It creates a modified firmware file with Bangcorrupt’s scripts, as well as modified sample and pattern files from the existing samples and patterns on your Electribe Sampler.
Additional Python script to adapt sample bank AND pattern bank to the HackTribe firmware
There is also a new Python script the notebook uses, but which you can also run locally on your machine: It takes an e2sSample.all sample dump file, and a matching .e2sallpat pattern dump, and adapts them to the HackTribe by moving all samples to User sample space. The patterns are then modified to find the samples in their new locations.
In writing the script, I had to document parts of the sample dump file. bangcorrupt did not want to have documentation as part of the main hacktribe repository to be on the safe side of hacking/reengineering regulations, so I created a separate documentation repository. It’s quite empty so far.
Isn’t it GORGEOUS? Classic Minimoog – less of a control panel, more of an erogenous zone for synth nerds. Tell me you don’t want to feel up these knobs! The pure beauty of a one-of-a-kind electronic instrument. The design and the sounds are still in highest demand more than 50 years after its design – and I was pretty sure I’d never, never even be tempted to buy one.
I never even wanted a Minimoog!
Let’s be honest: Moogs are ludicrously overpriced, and overhyped. Not a single classic Moog ladder filter sound you couldn’t do just as well with a modern plugin, or almost any modern hardware. Hey, even the R3 – my most underdog synth – can do pretty decent Moog impressions. And if you are with the “Digital-will-never-sound-like-true-analog” esoterics, there is still the option of Neo Old School: Using the old design with the upsides of modern analog technology. Get yourself a Boog, for fuck’s sake. (And a life.)
Still… as we know, it’s all about the workflow – and about that unique combination of how an instrument looks, feels, and sounds. So when I saw a Moog enclosure and front panel on eBay for a couple of Euros, I could not resist and had to buy it.
“It’s aliiiiive!” – How to give life to an empty corpus
Suddenly, the Mac did no longer click with me: The trackpad in my MacBook Air M1 (end-2020) no longer clicked, seemed to have jammed, gave no haptic feedback. I could no longer click any objects on the screen; without an external mouse, the laptop was unusable.
It was quite easy to solve that problem; some short notes might help you if you have a similar problem.
Fast fix: Activate “Tap to click”. Get a mouse and go to the Trackpad settings and set “Tap to click”. At least you can use the trackpad now with selecting things bei tapping them instead of clicking them.
It might not be the hardware’s fault. I did not realize it at once, but the click you feel when you click the trackpad is not produced by a mechanical spring but by activen electric components – a couple of small electro magnets producing the haptic feedback. This post by pocket-lint.com does a good job explaining the techonology. This means that it might actually a firmware or OS problem. I read that some people had success temporarily disabling all haptic feedback settings; give it a try.
It is quite possible to replace the trackpad if necessary. It is not really easy to take a modern Apple device apart, but it is feasible, provided you have the right tools. Remember that Apples patronizing “Genius Bar” technicians might charge you heavily. But: get the tools!
The right tools for fixing a Macbook Air. You will need them. I had Torx bits for mobile phone screws anyway and bought some more on Amazon. This is what you need:
a Pentalobe-P5 screwdriver for Apples 5-star-hole housing screws
a Torx-T4 screwdriver for removing the trackpad cable connector clamp
a Torx-T5 screwdriver for the trackpad screws
a magnifying glass
a box with several compartments to keep the 6 different types of screws apart and safe
good workplace conditions – proper lighting, enough space, a workplace mat
Taking the Air apart, step by step.ifixit does a brilliant job at explaining and showing every step – have the tutorial on a second screen next to your workplace so that you can look at every step when you need it. Pro tip: Read every step thouroughly before you do it – I didn’t at one point and missed that there are distance shims on top of the trackpad which drop to the floor when you take it out. Some rather undignified crawling ensued.
Apple supports your Right to Repair. Seriously. A little bit. „Right-to-repair“ laws have forced Apple to move. If you insist on trying to repair your iDevice, Apple gives you information, tools, and parts – provided that the iDevice is rather recent, and that you live in the US. But to be fair: You can find the comprehensive Macbook Air Servide Manual (PDF) for download. You may also order a replacement trackpad for about $100 in the U.S. Apple’s Service Support draws some criticism for its pricing and for its rather complicated procedures, but it is a start.
In short: This is what I did to get the trackpad working again
Bought the tools.
Opened the Mac and detached the battery connector. My advice: do that, then reconnect and check whether the trackpad is already working again.
Took out the trackpad and gave it some menacing looks, carefully poked at the metal strips, and cleaned what seemed worth cleaning.
Cleaned the trackpad bay in the housing to remove any object that might cause problems
Reinserted the trackpad. The service manual states that a new trackpad comes with shims in different thicknesses, so I measured the thickness of those I had and found that some were .1mm and some were .15. I inserted the .15mm ones to the front, and the .1mm ones up next to the keyboard.
Put everything back together. The critical moments: Reconnecting the battery connector with minmal force. Reconnecting the trackpad’s flat cable to the ZIP connector: open, pull out flat cable, reinsert, close locking mechanism. Reconnect the PCB connector plug for the trackpad next to the battery connector.
Triple-checked the connectors, then attached Macbook to power supply and switched it on. Worked.
I have been using Jenny as a bass synth recently, and I am quite impressed by the quantities of life and fun this old machine is adding to the mix. She doesn’t do that much in terms of tonal range, but what she does, she does well.
Drilling holes in Jenny’s front
I rediscovered an old trick when drilling metal: use a bit of alcohol, not on the person drilling, but on the surface you want to drill. And don’t go too fast.
Giving my JEN SX-1000 a bit of additional low growl by adding a pre-filter overdrive.
A nice little addition: Insert a booster circuit kit where the coupling capacitor between oscillator and the filter used to be. Come on, you’ll have to take out that damn capacitor anyway. And it sounds really nice, punching through the mix (samples below) – especially in combination with the sub-oscillator mod.
I do admit that you might think that this is a superfluous mod. After all, when you drive this circuit – any circuit – into overdrive and into clipping, the resulting wave form will, gradually, start to resemble a square wave.
But I could do it, so I did it. And I like it. So let’s get started.
