For my area of expertise I have decided to look at Impulse vs ReDrum, a battle between the two main drum instruments within these two software programs Ableton and Reason.
Personally I have used Reason a lot, I enjoy using ReDrum as it has an easy to use interface that allows much flexibility. However I am not too keen on Impulse although now having used it am less sceptical of it.
First of all here is ReDrum and Impulse
IMPULSE

REDRUM

On face value I think both seem fairly similar, however there are differences.
First of all the controls, Impulse in my opinion is the better instrument for controls, why? well Impulse allows the user to have control over panning, pitch, volume, start, stretch, distortion and filters, not only is that a good selection of controls but it also has global controls, which affect all drum samples within the kit allowing for even more control over your drums.
However ReDrum isn’t too shabby either, with the following individual drum controls; panning, pitch, length, start, tone, soft medium and hard hits, decay gate, volume and there are some global controls but not really the same style, more about the patterns.
Yes ReDrum uses a pattern sequencer built in, you can make a drum beat and listen to it without even arranging any MIDI at all. This is one reason I like ReDrum. However it has its disadvantages, Redrum will not allow unlimited patterns, however Ableton’s Impulse is based around MIDI and so is pretty unlimited as it doesn’t rely on the instrument to store the patterns, they can be stored as clips.
Another comparison is they both use a file for each drumkit, Impulse has presets and ReDrum has patches, this is not important however as it is just the words used for the same thing.
So how do we use these instruments? Well to make a drum pattern in each this is what you do…..
REDRUM
First of all with Redrum, set up the instrument within reason, by going into create… redrum drum computer… then from here you will see the ReDrum instrument as show earlier.

From here i can load a drumkit, known as a redrum patch. fromthe bottom left corner of the instrument.

From here your kit should load up and you can preview all the sounds available, maybe play around with the controls and see what you like.

(1) Allows you to preview sound
(2) Select that drum
Then you can use the pattern maker at the bottom to fill in the drums, for each drum you must remember to select the drum using the button labelled above(2).
Then you punch the pattern into the pads at the bottom like so:

As you can see Redrum allows you to have a soft medium or hard hit of the drum denoted by different colours, making Redrum in my opinion easier to use and get to grips with. However Redrums method of longer than 1 bar patterns is complicated, I found it really difficult to modify the amount of drums and amount of beats in the bar etc.
IMPULSE
I have already looked at impulse in a previous blog here:

However within Impulse, this is much easier to understand, here is a simple beat created using Impulse:

(1) Headphone icon allows you to preview sounds when lit
(2) Keys when headphone is lit preview sounds
(3) Timeline shows the drum pattern timeline
I feel that the timeline is a much easier to understand in the ableton drum machine, it is all based around MIDI however which i am not too keen on but it does allow you to see all drums inputs at the same time.
Another point I noted with ReDrum is the ability to split each drum channel up and put seperate effects and processors on these by accessing the wiring at the back.

This is a good feature and Ableton does not give Impulse this ability.
However Reason can be rewired into ableton which would slightly solve this problem.
So in conclusion, I would say that I personally like both, I prefer the look of ReDrum but i still appreciate Impulse’s versatility.
- Redrum is better for singling out drums for added creativity
- Impulse is good if you can easily use MIDI for editing and recording purposes
- Both are equally easy to pick up but also have challenging aspects
- Both have the ability to transfer samples into them from anywhere
