The complex simple delay

Submitted by mic on Wed, 03/28/2018 - 21:19

I use the words "simple delay" to describe the simplest of practical recording effects – an effect that produces one repetition of the input signal with some delay in time and usually with some decay in amplitude. More complex delays can have additional parameters: feedback, delay and decay sweeps, multiple "taps" to output, etc. Even simple delays, however, can be very interesting and the following are example settings that can produce great results.

Faster magnitude response computations

Submitted by mic on Wed, 03/28/2018 - 21:17

We were working recently on version 3 of Orinj. We wanted to improve the graphs of several of the DSP effects in Orinj to include the actual magnitude response of the effect. This included effects that have graphs with some equalization or some frequency type filters – the graphic and parametric equalizer, the reverb (because of its parametric equalizer), and the notch filter. This post is about computing the actual magnitude response quickly and efficiently.

Music and the brain

Submitted by mic on Tue, 03/27/2018 - 21:29

I just watched the 2009 documentary "The Musical Brain" – various neuroscientists studying the responses of the brain to the listening, composing, and dancing with music. Most interestingly, one professor (Daniel J. Levitin) studied what happens in Sting's brain when he listens to or composes music. Also interesting, Wyclef Jean was talking, using the sleepiest voice and expressions that I have ever seen, about how his eyes lighten up and how excited he gets when he hears or plays music.

About scale modes and guitar licks

Submitted by mic on Tue, 03/27/2018 - 21:12

Everyone knows some scales and can talk a bit about modes. A scale is a collection of notes in some ascending or descending order. The A minor scale for example is A, B, C, D, E, F, G. This scale has modes: Aeolian or natural minor (A, B, C, D, E, F, G), Locrian (B, C, D, E, F, G, A) and so on. There are seven modes of the natural minor scale in fact, one of which is the major scale itself. All modes contain the same notes though, so why do we care about modes?

Release of Scales version 1.0.0

Submitted by mic on Tue, 03/27/2018 - 21:03

Scales is a piece of software for your mobile designed to show you various scales on various instruments and the chords that belong to those scales. I built Scales, because every time I get together to play with different people they pick different songs (I am pretty easy going) and then start wondering about what scales those songs are in, how to play various chords, and so on.

Guitar practice – some licks

Submitted by mic on Tue, 03/27/2018 - 21:00

My last post was about practicing guitar. This one has some of the simpler licks that I practice regularly. I have always wanted to start a collection of nice guitar licks and here is a start. I like the ones below as they do not use complex guitar techniques: no arpeggios or shredding, not too much movement up and down the neck, simple fingering and barring. Plus, these licks sound good and are very common. I enjoy blues improvisation and so these licks are bluesy, but we will have time for rock licks later.
