Yes. The free tier does everything to build, hear, and print a chart: up to 25 charts, real sample playback, a metronome, markup, offline reading, and browser print to PDF. Pro adds unlimited charts, Gig Blazer setlists, AI chart drafts and MP3-to-chart conversion, and one-click PDF downloads including a whole setlist as one file. $59/year or $9/month, with a card-free 30-day trial on every new account. The trial comes with AI credits so you can try both AI features before you pay, and the pricing page has the current amounts.

Two reasons. First, a chart isn’t sheet music. It’s the reminders a drummer writes for themselves: sections, bar counts, a groove where it applies, and cues to find your place. Nobody writes out every bar. Second, every chart is one drummer’s plan for one gig. Bands cut verses, repeat a chorus, or bring a section down, whatever the song and the musical director call for. A chart is that drummer’s version, not a transcription of the original recording. If a community chart isn’t quite your arrangement, clone it and change it to match.

Some charts describe the groove in shorthand (“4 on floor”, “16 hats”, or a row of letters like K--- S---) instead of notes on a staff. It’s usually a tool limitation, not a preference. The app the chart was written in had no drum notation, so shorthand was the only way to write the part. It also reads faster on stage: “4 on floor” is quicker to read than a bar of engraved sixteenths, and some drummers prefer it. ChartBlazer engraves real drum notation, so anywhere you want a groove spelled out you tap it onto the step grid and it appears on a staff. Both live in the same chart, section by section. Keep whichever reads faster for you.

A chart is one row per song section with a representative groove; a flow chart, every bar on a staff, writes the whole song out bar by bar, wrapping across the page like sheet music. Neither is more accurate than the other, just a different way to read. Pick whichever is easier for you. Both are free and count toward the same 25-chart limit, and a flow chart doesn’t need every bar notated: blank bars carrying nothing but a cue or a pen mark are a normal way to use it.

A brand-new account can make one chart to try the editor. Verifying your email (free, one click on a link we send you) unlocks all 25 free charts. It also protects account recovery, so it is worth doing right away.

Yes. Everything you create is yours and stays fully editable forever. If a trial or subscription lapses, you keep every chart. You just can’t create past the free cap until you’re back under it or subscribed.

For reading, yes. Open a chart or setlist online once and it is cached so it opens offline later. Venues have bad wifi. You can install ChartBlazer to your home screen like an app. Editing while fully offline is on the roadmap.

It is built tablet-first: big tap targets, inline editing, and pressure-sensitive stylus markup. You tap grooves onto a coarse grid, never by dragging tiny noteheads on a touchscreen, and ChartBlazer engraves the notation for you.

Free accounts print through the browser (the Print menu, or File → Print). Pro adds a one-click download: we render the PDF on our side, so you get a finished file with no print dialog to set up and the same page setup every time, and a whole setlist comes down as one PDF. Both print the chart itself: sections, cues and notation, re-laid out to fill the page so the notation stays big enough to read on a stand. Pen marks and highlights stay on screen, and a Description toggle in the Print menu decides whether your working notes come along.

Share a private chart with your band by @handle or email: they can view, play, print, and clone it without it ever being public (sharing privately is a Pro feature; receiving a shared chart is free). Or publish it to the community. Either way the people you share with can clone it: they get their own editable copy, and your original stays yours.

Yes, that is what ChartBlazer is for. Your chart is your own reading of the song: its sections, bar counts, feel, and the grooves you would play. The one thing to keep short is the Cues column, because song lyrics belong to their writers and publishers: use a fragment that tells you where you are, not the verse itself. The Copyright page (linked in the footer) has the details, and explains how to ask us to remove something.

You don’t have to. Browse the community and clone any public chart into your account: it becomes your own editable copy, and that is the quickest way to start from something real. There is also a worked demo of each format under “samples” on your chart list: read one, play it, and use it as a template for a new one.

Upload a PDF of the chart on the AI page. The upload box takes a chart, a photo of one, or pasted text as happily as a recording, and it comes back as an editable draft: the section names and order, the directions and the cues read from the sheet, with the grooves drafted for you to check. When the sections can be read off the sheet, bar counts follow it: a count it states, else one bar per printed line of a sung section, else blank. We leave a box empty rather than guess. Add the recording as well and the bars are measured from it. If a chart won’t convert, send it to support@infoblazer.com and we’ll do our best to convert it by hand. Every app’s PDF is a little different, so no guarantees a given chart will make it, but anything that converts lands in your account fully editable.
