How can I do a slow lfo. I can modify and compile VectorLfo but I don’t know how to make a long lfo (more than 1 minute).
Can you tell me some way to do it? Thanks.

My first question is any advice on compiling my own firmware? I’ve seen some posts in this thread around arduino software and compiling the INO file, but anything I need to watch out for in terms of compatibility or anything like that?

You do need to use the Arduino IDE 1.8.1 and Teensyduino 1.35

My second question, more tactically, is what is the name of the file that has the code for ShiftReg. It seems to me that most of the applets have their own files, but I can’t seem to find one called ShiftReg.

It’s called HEM_TM.ino. ShiftReg used to be called Turing but, after a discussion with Tom Whitwell regarding the use of his trade name, I changed it to ShiftReg out of respect for his preference that “Turing Machine” (or variants thereof) not be used for anything not sold by Music Thing.

As for the VOR stuff, see the ocplus branch in the repo. I can’t promise that that branch is complete; in fact, I’m sure it’s not. But it would be a good starting point for getting the VOR working with Hemisphere.

Sorry for the late reply, but it’s 2020. :slight_smile:

hi all, i was curious if anyone could offer some trouble shooting or point out a simple error i’m making >.> i’ve tried two different versions of hemisphereand in both i’ve been unable to change the app on the right side (it’s always fixed as scales duet) the fact its happened with two differnt builds leads me to believe i missed something when i was learning to use it, or something is wrong with my O_C - maybe a tact switch is malfunctioning?
thanks for any advice!

#111

When you click the right hemisphere button, does an outline appear around the Scale Duet applet?

#112

no thats the issue - i[m going to try to install the flipped version to see if its a firmware thing or if the part on the OC is broken

#113

It sounds like a hardware issue. Make sure that the Teensy is seated firmly in its socket. If it is, you’ll probably need to get out a meter and make sure that the button is closing when pressed.

#114

i think this is the case, tried the flipped hemisphere and the other button worked. going to be replacing the tact switch tomorrow -_-

#115

loved IT! amazing work!

#116

hmmm replaced the tactile switch and still no results :confused:

#117

Did you test the switch with a meter before replacing it? There’s not much point to replacing a part that works…

#118

I have a similar issue and concluded it must be encoder related (also right encoder not switching apps). I am currently still looking for a replacement but it is not on top of my list of tasks.
I am curious what you come up with (mine is a nano/micro o_c I bought through the marketplace).
My full size o_c does not show this behaviour running the same firmware.

#119

I am not sure if this is helpful, but I got around to swapping the encoder on mine with success… though only after calibrating the unit properly.
I started with a fresh teensy so it was in need of calibration.
In hindsight I think it only needed the encoder calibration though (the part where you define the direction.
The easy thing though is that the encoders as well as the included button pins are directly connected to the teensy pins, so just checking for continuity helps in trouble shooting.

I started with a fresh teensy so it was in need of calibration.

Keep in mind that Hemisphere Suite has a backup/restore application, so you can dump your data, including your module’s calibration, to a MIDI librarian, then restore it to the new Teensy. This way, you don’t need to muck about with calibration just because you changed your Teensy. (Of course, calibration data is only good if you’re using the same module)

which Hemisphere applet would one use to recreate a s&h function? is that possible here?

i dont exactly understand how the shift registers work on here. for something like enigma jr or the dual quantizer, is there a way to send a gate into one of the inputs which will then track and hold the incoming cv sequence?

#122

I’ve been using the Dual Quantizer with scale set to ‘off’ - I believe this effectively turns it into a S&H (within limitations of the O_C voltage output range)

Calculate has a sample/hold function (needs to be clocked or triggered)

Umm, I’m totally new to my 1u O_c 4robots and I don’t seem to have all the apps listed on the hemisphere page. I have 52 toital. Captain Midi is not there for example. Neither is “Setup” or “Backup and Restore”. I tried flashing the latest firmware from the plum audio site but no luck. Am I missing something?

#126

Are you accessing the app selection screen ? It will load you in to hemisphere by default but you need to long press the right encoder to access full applets like Captain MIDI/The Darkest Timeline/setup etc

#128

that’s it thanks. I feel dumb now. haha

#129

Haha all good man I made the same mistake when I was looking for Captain Midi the first time
