This is pretty awesome. The UI is beautiful and intuitive. I tried a bunch of these simple music tools and this is the only one that really invited me to start creating something.

I wish I had copy-paste though, is there?

(+2)

You do have copy-paste but there is a bug where you cant use the keyboard at all and you need to refresh the page.

Can you add the function of importing the MIDI file?

man I wish I could use it in my desktop-not-browser :')

(1 edit) (+2)

Can you make it for windows, mac, and Linux

I love this lil sequencer so much! It's so intuitive, sounds fantastic, and is just adorable to use -- thank you for making a great and beautiful tool!

(1 edit)

This tool is amazing. The design and concept are perfect. If you added the option to use it offline, and perhaps to add custom instrument packages, people would go insane with it.

Edit: Nevermind, I see that you already posted an instrument editor for this... I'll have to dig deeper!

Very cool but a downloadable version would be very pog

This is perfect ! I love it :D

Would be nice if we could save the "file" of the song to continue to edit it another time/on another pc or some, idk if it's already possible.

Thanks :)

this  is so pog

Here is a song I made with this :) https://cdn.discordapp.com/attachments/373184311131766804/963386980010426378/song4.mp3

Not bad; sounds like Titlescreen Music to me.

(+1)

Thank you :) I love simple tools like this where even I, with my very limited knowledge in that area, can create something interesting.

(+1)

Welcome, and same here; I know very little about making music, so I understand where you're coming from.

Wow! Great tool! A little bit small viewport and browser only. But the sounds are great and fun to work with. Thanks!

(+2)

would it be possible an offline version?

when i export it to mp3 it wont download

To be honest, I agree with Pizzabox2006. An f-zero instrument would be pretty dope.

F- Zero please snes

good

how do select notes

(my mouse doesn't work)

well, you gotta use right click and drag.

(+3)

This is fantastic! I absolutely love it. I do wish there was an executable version with fullscreen for easy of use, but it really is great.

(+1)

i think all this needs is to have a fullscreen option. mighty fine tool though!

(+1)

And when you make it a Linux-available executable (as suggested by Teafan), will you reveal the format the instrument sets are in?

I'd love to import some others.
(MOTHER 3 has the most realistic sax, trumpet, and electric guitar I have ever heard in a 16-bit game)

this might easily be my favorite easy song maker out there 

incredibly versatile, easy to pick up and use, customizability off the charts, just got everything completely right

if you plan on making this into an executable that would be great! it would be a pretty useful tool

also could you maybe make it so that you can export your song as a midi?

(+2)

Are You ever planning to make this an Executable and release it on Linux? 

I'd love to use this tool offline

i have been serching for over 5 months for the a easy to learn music program to make music for my game, thank you so much for making this

The play button or pressing space doesn't seem to work in firefox /: other than that it's a cool tool

This is so amazing!

Are you planning to port it to other platform like desktop or mobile app?

mate this is the coolest online editor ever , it would be pog if there was a desktop download version :D

and the UI oh my gosh so satisfying 馃ぉ

(+1)

this is so awesome ! thx alot 

(+2)

could you add cmd+a to select all?
thanks.

The solution of FamiStudi

Very very cool! Thanks for this fun little tool.

Just a little "problem", when you export in Mp3, the rhythm is changed, I guess it's already a known problem, but just in case ^^.

But otherwise, it's really fun!

Well done!

yes, i think it gets a bit slow, but it's really a good tool. 馃憤

pls try update only that

and maybe, you can add drums other than the 2 drum box.

It鈥檚 quite a fun and nostalgic little piano roll.

everything is great but how do you load in a song if you wanna work on it more?

(-1)

Simply drag and drop the song file onto Petaporon UI to load it.

is anyone else noticing a difference in quality when you export an MP3?

yeah the song seems to slow down sometimes

I really love the look of the UI!

Yeah this is so cool also hi frand!

Ahhh, hello! :D

(+1)

I can't figure out what the groove buttons do, please help

it seems the farther you go to the right, it turns up the amount of "swing" 


Swing—sometimes called Groove or Shuffle—is the addition of tiny delays to every other hit of a beat.

(+1)

is there any way for me to download this for offline use? I love it!

(1 edit) (+4)

Yes, using the itchio desktop client

I just keep coming back to play with this!

I have a couple of ideas:

The Super Mario Sunshine acapella soundfont and the Minecraft soundtrack instruments would make great instrument packs to play around with.

Fullscreen option?
Maybe also the ability to increase/decrease the octaves
on the piano with +/- buttons?

I am a dev with some background in music -
would love to talk more about this with you.

Everything you've done up to this point is solid, thanks for putting it online!

Doesn't work on Microsoft Chromium Edge. Seems like a great tool, bookmarked in hopes the bugs are ironed out.
