Chords mode in OP-Z app! (and how to make a Videopak)

[@enfinitesimal2810]

This is amazing! I had no idea video packs could receive touch input and send midi back to the OP-Z. This opens up a lot of possibilities for midi in that wouldn't be possible live without an external controller. For example, you could do a build up on the performance track OP-Z, then trigger the "drop's" pattern using your device.

[@mochreach]

That's a cool idea, and it's totally feasible. It would be pretty straight forward to listen to the midi coming out the OP-Z and then send midi in response under certain conditions.

[@60400]

Man, I had no idea this was possible. I got a Roland J-6 mostly as a workaround for something similar. Great job!

[@mochreach]

Thanks, glad you found it useful!

[@mairinger80]

YESSS! We need more tutorials like this… this opens up so many possibilities. Until now I thought videopaks are a one way street, just receiving midi from the OP-Z. It would be great to get an overview of all the functions and inputs we can use in the Klak framework…

[@mochreach]

If I get some time, then I'll try and put one together!

[@videolabcreators]

Bravo! This is great, especially dig the walkthrough and the ARP mode looks really fun!

[@mochreach]

Thanks very much, I appreciate it. Also, thanks for putting together the tutorials on your channel, I found them really useful when I was making this.

[@CrittendenIV]

You're amazing! Thank you! I am just now getting into the OP-Z. You have provided me a lot of possibilities!

[@mochreach]

You're welcome! The OP-Z is amazing, it can do so much. Let me know if you have any questions about it and I'll help if I can.

[@spiegelkind2387]

Ugh, got that Unison midi scale ad before this lol. Great OP-Z update though!

[@mochreach]

Hahaha! I should have sold it as a premium chord pack. 🤣

[@CensoredStudios]

I just want to say thank you so much, I am like you, and love music, and want to make more, but aren’t very musically inclined. This is genius and helps me make stuff that sounds great, and learn while doing it. Looking forward to seeing what you put out next

[@mochreach]

You're welcome, so glad you've found it useful!

[@Xenious]

Very cool!! It would be interesting if it could make the keys light up on the OP-Z itself to see the individual notes.

[@polyphant]

This is absolutely awesome!!!!! Thank you so much for going to the time and effort! I'll be making good use of it :)

[@mochreach]

You're welcome, I hope you enjoy using it!

[@polyphant]

@@mochreach Battling the mountain of chord theory atm, so this is wonderful timing for me, really thank you :)

[@SONWU]

Wonderful work, I'll need to install this one!

[@SONWU]

I just tried the videopack and I already love it a lot.!!! Thanks for making it 🙏 I hope you don't mind me mentioning a few things that could be improved... 1. I use it on an iPhone11 and the interface seems to be all over the place. 2. It would be nice to be able to trigger the chords from the keyboard itself. 3. Minor Detail: app design could be improved by using some BB STRATA or BRIC SANS font to make it look more in line with OP-Z's design language.

[@mochreach]

Thanks for the suggestions. Is there any chance you could take a screenshot of the interface on your iPhone and upload it to an issue on the GitHub page? I don't have any Apple devices to test it with.

[@SONWU]

@@mochreach Done!

[@mochreach]

Thanks, I'll take a look at that in a few hours and see what I can do.

[@SONWU]

@@mochreach My pleasure!

[@rockrobertson5776]

Brilliant! Thank you, downloading❤❤

[@AndyDSmithuk]

Thanks dude, you're going above and beyond with these vids. I sometimes feel like the OP-Z was sent from the future, perhaps you are also from the future? 🏴󠁧󠁢󠁳󠁣󠁴󠁿

You're very welcome, I'm glad you've found them useful! Slightly worried that I'm a Terminator now... 😁

[@lburger404]

This is awesome! I might try to make something like this in the future.

[@samprock]

That’s totally awesome! Is there a way to add actual chord names under number? (i Dm)

[@mochreach]

No, not at the moment I'm afraid.

[@DudeWithADrone]

This is an amazing game changer. Thanks loads Mo. I have one question and if possible a feature request. Are triads and their inversions the only chord types possible. By that, what I am really asking is can this be modified to play four note chords? I was thinking about some of the neo-soul type chords for lofi music. Also I just saw the other video about the bending and the foam strips and double triggering. Fantastic! You should contact the "Free Beats" guy as he seemed genuinely depressed that his has become unusable. Thanks again matey. This is impressive.

[@mochreach]

You're welcome, glad you like it! Yes, it's definitely possible to add 7 chords and other types, there are also lots of scales I could add. Hopefully I'll get round to it at some point in the near future! Regarding Free Beats, he's said in a couple of videos that he's tried fixing the double triggers with that method, but didn't have any success. Not sure why!

[@DudeWithADrone]

@@mochreach that’s fantastic and you totally earned my sub. I was actually wondering the other day if a couple of sticky feet in the middle of the baseplate might prevent the OP-Z from curving. The baseplate should be bonded to 0.5mm stainless steel. Now that would keep it straight. I know a steel guy. Maybe I’ll make that happen.

[@mochreach]

Make a video if you do get that fabricated and let us know if it works!

[@jazzspastiks5566]

@@mochreach Amazing work! Would love it if you could add those types of chords too :)

[@johnfarrell3506]

Great video. The Locrian mode cracks me up. In order for the modal structure to be complete it "has" to exist. Its not exactly a playable scale. Its essentially the scrape pile of modes. Those notes weren't used anywhere else, they all sound like shit in relation to each other, but they're stitched together like Frankenstein's monster to create a dissonant, and unholy scale.

[@mochreach]

Yup, the monks didn't use it as a choral mode but it's such an obvious omission! I definitely struggle to see a good use for it, I always accidentally end up in a different mode when I use it! 🤣

[@lukemaclean4606]

This is awesome! It would be amazing if there was an empty bank for programming your own set of chord voicings per project.

[@mochreach]

That would be neat, unfortunately you wouldn't be able to store them after the app closes. As far as I'm aware, the only way that the videopak can store data is by reading the state of the encoders. So it is possible, but the saved chords would be temporary.

[@brodiecole8856]

Incredible work!

[@Lowlandbeatz]

Great work… is this app only for reference ? Or can I use it for my beat making !

[@mochreach]

You can use it now! There's a link in the description to where you can download it, along with information on how to install it into the OP-Z app.

I am looking forward to your generative ambient project. Hope that you get around to it soon.

[@mochreach]

Glad you're enthusiastic! Working on something else at the moment, but that should be out soon. Once that's done I'll move onto the generative project.

[@rolfjohansen5376]

This is really inspiring ... wonder wonder, can I utilize scale, modes in a certain way to provide chords for my playing or send chords to my Tyros accompaniment keyboard

[@mochreach]

Maybe if you send the midi through the opz to your device, not sure if that's possible though. I'm going to add chords and scales to MIDI Surf soon in the "Theory Craft" update, due towards the end of February, which you'll be able to use with any device. I'll ping you a message when it's ready, if you're interested.

As an idea for an update you could add + and - buttons to access the octave directly while editing other tracks

[@ceverett5972]

Thanks. I’ve installed this and it works. How do you get to the second page to manipulate the Chx channel in green at the bottom?

[@mochreach]

You press the shift button, white LEDs for the first page, yellow or green (not sure which, I'm colour blind 😬) for the second page.

[@ceverett5972]

@@mochreach Thanks. It’s the green page.

[@peacefulpigeon7254]

Hi this is great! I downloaded it and all works fine but sorry I don’t know what you mean by the second page? I have tried shift on the opz and then tried to find the second page by scrolling on the screen of the iPad in the motion page - a bit puzzled thanks so much cheers

[@mochreach]

Glad you like it! By the second page, I mean the second page of parameters on the videolab track of the OP-Z. Select the videolab track with Track+[camera], then press shift to cycle through the pages of the parameters. There are 4 pages of parameters, when you press shift it will cycle through them and a number key will light up displaying the current page.

[@peacefulpigeon7254]

@@mochreach hi thanks so much - first time I’ve used the motion section of the opz app and got confused…It’s great fun to play with and all works as it should! Loving it.

[@sdsinatra]

Super cool, thanks! For some reason I can’t get the ARP to work on the device when pressing a chord in the app. I’m new to the OP-Z so surely it’s user error. Any tips/tricks?

[@mochreach]

Did you set the channel to 7 on the Chords Mode videopak and does the arp work fine when you use the keyboard on the OP-Z?

[@sdsinatra]

Got it! Should have paid closer attention to the video. Thanks!
