Hi,

I'm new to MODX8.

I want to create pattern only with drum kit without any performance (sound), so I can play this new pattern like any other built-in patterns.

Any help please.

I’m going to guess that what you are attempting to do is create your own Drum Arpeggio Phrases.
Basically, you can use the built-in Performance Recorder to create the data, it can be converted to a User Arp.
Once data is in the Sequencer (either Song or Pattern) it can be converted using a special routine to a User Arp; you can Name and store 256 User Arp’s in the User Bank.

How to Create a Drum Arp
You can use any Drum Kit — the Arpeggio Phrase that you create will be, when finished, accessible by any MODX Drum Kit — So the sounds you use are not a permanent part of of Arpeggio data, the Note number *is*.

Most Drum Kits feature the two octaves of Notes between C1 and B2 as the Drums that give the Kit its name. The principal drums — if the Kit is called a Brush Kit, the Notes between C1 and B2 will reflect this; if the Kit is named Hip Hop, these Motes will be the main sounds.
Most Drum Kits feature the octaves of Notes above C3 for Latin Percussion and additional sound Fx.
Most Drum Kits feature alternate sounds C0~B0 including drum roll, side stick alternates, etc.

This standardization of mapping makes it possible to use different Drum Kits for the same Arpeggio data.

When creating a Drum Arpeggio you can use 16 different Drum instruments (a 16-piece Drum Kit).
Choose the Kit you want to start with

From the HOME screen press [RECORD]
Select a blank Pattern, Scene 1
Set the Tempo and Length parameters
Set the Time Signature if not 4/4
You can choose to use Record Quantize (or you can Quantize after recording)

Record your drum groove. You can drop out of record (Rehearse) by simply tapping the Record button (flashes).
Drop back into record by tapping it again.
Hold [SHIFT] + [offending Notes] to Erase them - real-time erase

Once you have your drum groove recorded, you can apply Play FX, Quantize, etc using the “Edit/Job” functions
One of the Edit/Job functions is “User Arp”

You can convert your Track (Track 1) to a User Arp
Set the Start and End Measures, for example, if you record a one measure Drum groove the Start = 1, End = 2
If you record a four measure drum groove the Start = 1, End = 5
Be sure you give a Category, SubCategory, and Name. You will need to find it again in the future.

Set the Convert Type for Track 1 = FIXED
This means the arpeggio type when recalled will play exactly the notes you have designated (fixed notes).

Your USER ARP is assigned a Number 001-256 and can be assigned like any other Arpeggio.
When you are on an ARP screen you can press [CATEGORY] to view the Category Search for Arpeggio Phrases (purple). There are 10,239 Preset and room for 256 User. Set the Bank to User to view your creations.

Any .mid can be used as a source for Arpeggio Phrases.
The typical drum arp uses Fixed Note convert type

Thanks, but I need only to create my own beat and a new pattern Drum rhythm using un existing Drum Kits (like these patterns already saved in the keyboard) and not Arpeggio , when I try so save , the problem is I'm getting the same rhythm that I have choosed and not the one I created.

"... (like these patterns already saved in the keyboard) and not Arpeggio..."

That's going to be hard because the built in drum 'patterns' ARE arpeggios.

If you mean you like to record a drum sequence and then play it back and play along, both the Song or the Pattern record options will do fine.

Bad Mister described how you can create an arpeggio from what you recorded and once saved as a User Arp, you can select that arp to play in the drum Part with Arp Hold on, without playing back a sequencer recording.
