manually. i’ve been using trackers long enough to be able to see where the notes should go, so it’s just easier than buying and learning to play a keyboard to a decent standard.
i spent 100 quid on a midi controller for dnb bass lines and melody work - then found renoise and haven’t touched it - or dnb since
Both, with QWERTY. :-]
edit: LAPTOP…
90% live, midikeys&padkontrol
5% data
5% accidents
I sure could use some kind of quantize, or piano lessons, I hit the right keys, but never at the right spot, and playing 2 hands leaves a lot of notes to reedit . Sometimes I make some fast melody’s in cubase or live and then load them as midi but mostly I am too lazy for that.
programming only. no way in hell will I play my melodies live and waste the tightness of a tracker.
EDIT: actually, I learned to play actual KEYBOARD… not keyboard, but KEYBORAD… that’s right, that thing that comes with a puter… I play it
just entering data… melody is in my head, there’s no need of MIDI keyboard for me…
I only just enter programming data.
I would like to be able to use a midi-keyboard but it doesn’t work that well in Renoise.
I’m going to dig up one of the bundled cubase sequencer and import the MIDI file into renoise.
One thing that is rather nice with a keyboard is that you also get the “personal touch” since each key don’t get the same velocitity etc. in one go.
I enter all data in manually. though I have a (very old) midi-keyboard, I’m not a keyboard player and I find it much easier to just program in the notes.
trackeresque-step-sequence with alphabet, numbers, down arrows, caps lock, ins+del and backspace
I also use blocking alot
i have a midi piano, but i know qwerty much better 
it doesn’t matter what you use! pick the melody your ears like, and put it in whichever way works best for you 
Entering manually: 95%
Entering with MIDI keyboard: 4%
Importing as MIDI from other tools: 1%
Mostly plain tracking.
Occasionally playing chords on my nylon.
And it’s a long time since I touched the keys. I’m not very good at it anyways.
I need a PC-keyboard with velocity sense and aftertouch.
…for music you thought? No, I need it to humanize the size of the letters and spaces while I’m writing texts.
hahaha
Haha you bunch of nerds!
Play the notes in live! Makes so f****ing much difference to your music!
Crytek has the right idea, play it in then correct where you want!
It’s the one thing I love so much about trackers: you can sit down, take your time
to figure out EXACTLY what your melody should sound like, then put the right notes
on the right places by hand for getting that perfect atmospere, recreating anything that
goes on in your mind, without having to worry about lack of playing/composing skills,
because EVERYBODY van play a tracker and you nevvah need to worry about having to
re-re-re-re-re-record your stuff.
It makes no fukking difference, except it takes longer. But you shouldn’t rush art anyway.
Even though I have a midi-keyboard hooked up, I mostly step-sequence my stuff using the qwerty-keyboard. It is (unfortunately I guess) the fastest way for me to get the job done without errors. 
I guess the midi-way works with basslines, leads and other monophonic lines, but I don’t like the way chords are entered into Renoise, as I in most cases prefer that the lowest notes is to the most left, and so on… instead of which key I hit first.
^^^^^
70% step-by-step
20% recording with a midi-keyboard and edit later
10% record with a midi-keyboard to wav and play the sample.
I enter all notes on a keyboard when creating melodies and such.
I notice some people don’t really make melodies and just kind of cut and paste a bunch of samples around. Using the keyboard for that is fine. When you are actually playing various notes I personally find a keyboard in my opinion is much easier.
Sitting with my computer keyboard and running my fingers across it trying to come up with ideas doesn’t sound overly sexy.
