Wow! Messing around with this one, very cool! Maybe it’s more focused on realistic drum sounds, but I try to bend it towards a more techno-ish vibe, let’s see how far I am getting with that.
Compliments to the dev for providing a demo version!
-It would be nice if double tap on a control it would reset to it’s default setting.
Hi,
developer here.
Thanks for the nice words.
Feel free to leave your feedback here and I will try to incorporate suggestions and feedback in a next release.
This sounds really really good. The mutation options are fantastic!
This looks too interesting to pass up. (also a fan of Bleep)
Awesome app! Mutate option is fantastic and sounds really good. I noticed the chance feature seems to not work unless that is a result of me using the demo or failure on my part. When I lower the value to nothing, I still hear a sound. I should clarify, using the standalone app.
Great job! Definitely plan to purchase.
this is awesome!!!! ( a small but very bright speck in a darkening world
)
for those who have Fosfat and spatializer try putting those on your drum channel(s), for individual outputs ( MULTI OUT WHOOT!) or on the whole shebang...
lots to explore
Yes, I couldn't find a very elegant way to achieve all the options I wanted to have in the app. So I understand it's a bit confusing. There are actually 2 mutation systems under the hood. There is the system that uses the "chance" and "intensity" settings that are controlled by the user in the sequencer (what you are referring to), and there is also an internal vocabulary or groove system where I've programmed a vocabulary that would be used by drummers. With the "Vocab." knob you can control which system has the upperhand. If "Vocab." is turned down, then the system is using the "chance" and "intensity" settings of the sequencer. It "Vocab." is turned up, then "chance" and "intensity" are not used at all, but the internal drum system is used.
Awesome!
Very efficient UI/UX design and workflow! Having such easy access and interaction to those parameter lanes really allows for dynamics to shine, which has ALWAYS been the biggest Achilles heel of drum machine sequences. At least without a lot of tedious tweaking.
The shuffle time is great as well! I don’t know if I’ve ever seen that before.
Since you asked, here’s a few initial ideas… (It seems the design goal of this was to be more generative, in which case perhaps you intentionally don’t want a bunch of granular controls, which is cool too)
1) Length… maybe make it more obvious in the sequencer where the range is for each voice. Perhaps dimming the insactive steps? And if I’m being really greedy, having each modulation type have its own length per voice would make this just about the most powerful drum synth sequencer out there short of rolling your own in eurorack or Drambo.
2) Add some sequencer “tools”. Like the ability to shift a sequence type left, right, etc. but also some generators like in DrumComputer et al that will invert steps, add ramps, waves, etc. the ability to adjust all,steps up down in gang mode would be useful. I wish DrumComputer had that for their mod lanes. For sure a “clear” button and a “random” button would be cool.
3) when jumping back and forth from sequencer mode to synth mode, remember the voice being worked on… for example, if I’m sequencing the snare, when I switch over to the synth screen, have the snare the active voice.
4) I’d like to see a parameter lane for elektron style x:y “probably”… or like how OCTACHRON does it . Play 1 out of 3 etc. And if you go that direction, the ability to have negated states as well is very useful. So ‘NOT the 2nd out of five’ as an example.
5) modulation- having the ability to build modulation for each parameter would be cool. For instance, modulate overtone pitch with velocity, or noise with velocity.
6) small ui tweak… If a parameter lane for a voice has any non default values maybe have a treatment on it’s button to make hunting down where that weird sound is coming from.
7) an idea for the sequencer… in manual mode, maybe make it so a long press allows the sequencer page to be edited, but not played so you can build variations on the fly and THEN switch to them when you want. Makes it a little more “jam
This thing is what I was really hoping Moto Akamai was before I was so disappointed in its interface and the fiddle synth engine.
Great app! Absolute no brainer purchase.
Chance is not really “chance” like most other drum machines or sequencer…
Thanks for the extensive list. I will definitely try to work my way through it.
I hate the formatting on this forum…
Understanding Markdown can help with that.
Another thing, if possible, make the individual outputs “prefader” so that the mixer in the AU doesn’t have any impact on the level, panning, etc. That allows swapping presets during live use and not having to worry about one more variable (oh crap, the kick is muted in the AU mixer!)
Ooooh. I really like that it supports Intel Macs too.
@janm31415 Are you a drummer? Your implementation of the glitch/groove variation scheme with the “space” knob, the shuffle option all point to someone that “gets it” in terms of drumming…
I’d like to understand more about the mutation options…
I assume RLK is the ol’ right/left/kick (you gotta be a drummer) but what’s 4-2?
I’m also kinda curious about the design decision to have the 16 “pads” but only 8 addressable voices via the sequence… It’s cool you can trigger them all, but I can’t figure out how you’d control volume etc of voices that are not assigned to the sequencer.
Doing my best
. I started about 1.5 years ago, but so far I have been practicing for about 2 hours a day. But I've been a musician since I was kid, learning clarinet and guitar.
Bug?
Overwrite + Random eventually just drives all the values to zero and they never go back up… Am I missing something?
👏🏻👏🏻👏🏻
Difficult to say
. Suppose that all your "chance" steps are set to 0. And your "Vocab." knob is turned to 0, then "overwrite" or "mutate" will bring all velocities to zero eventually if the "Mutate" knob is not 0.
This is some of the best drum synthesis I’ve heard on the iPad! Amazing job. The sequencer’s very fun too! Took me 5 minutes of playing with the demo before I knew had to buy the full version.
One thing: It could be amazing, if you could store single sounds also (instead of a full kit only.)
I've only spent a little time with the app, but I'm a bit confused about how to handle closed vs. open hi hats. I'm used to having separate hits. I imagine it has something to do with using options in the sequencer, but then I wonder how to handle that when sequencing externally.
The open or closedness of the hihat is arranged with the decay parameter. In the sequencer, select hihat. Set your hihat hits with the velocity parameter, and control the openness of the hihat with the decay parameter in the sequencer. In this way it behaves more like a real hihat where the open and closed tones come from the same instrument. Your open hihat sound will stop sizzling when you play a closed hihat sound.
Thanks, that helps. A bit difficult for using with external sequencing, but that's OK.
Maybe the following might also work:
If you use a sequencer that sends midi to the jAmp Percussive app, then you can just make two hihats that react to different MIDI input signals. If you don't use the internal sequencer, then it is not necessary to use the "hihat" naming (which essentially just assigns a channel to the internal sequencer).
And another scenario: if you do use the internal sequencer but don't want to use the synth sounds (the internal sequencer can be used to trigger MIDI events for e.g. a sample based plugin), then reuse the ride channel as a second "open" hihat channel.
Ahh. Yes that’ll work. Thanks.
Great stuff, instant fun and really got a life of its own. Any chance a portrait mode could be added for the iPhone? It kinda works fine already in AUM but I’m sure a little layout tweak would help… maybe some indication of beat/bar in the sequencer would be handy too? (Just every four beats for quickly eyeballing them)
Wow, just had a quick play with the demo on iPhone and this is fantastic. No offence to AudioModern but I'm much more excited about this than PlayBeat 4. Will be purchasing. Kudos @janm31415
Apologies for my ignorance on the chance button. Thanks for clarifying.
Fun app!!
It's always baffled me there aren't more physically modelled drums - they seem like prime candidates for modelling solutions. This is proper quality and I'm looking forward to digging in deep.
See the comments section for a few detailed and useful clarifications from @janm31415 on things I found confusing. There's quite a bit of room for headscratching with some aspects of the app. A slightly more detailed manual catering to non-drummers would be ace.
Sounds great tho, really fun to tweak, excellent that there's a demo mode, and I'm excited to explore the 'groove' mutation settings more now that I understand it a bit better!
