Slowing Down tunes and looping parts of them for practicing

I remember those days a music student was advised to buy a cassette player with a speed /pitch control (I think I remember marantz made one of these, bingo I found one here, exactly as how I remember) knob so one could slow down tunes to transcribe them (or at least the "difficult" parts).

One of the biggest drawbacks of course was that by slowing down you also altered the pitch. Logically lowering to half speed made the "music" sound an octave lower! In practice it became a transposition exercise at the same time :-). Not very confortable. These days are gone (I am glad they are), since the slowing down can now be done by your computer!

One of the free tools that just does this is BestPractice.

BestPractice is capable of the following:

- Slow down and speed up the music
- Alter the pitch (so you don't have to tune your guitar down for those
Hendrix Tunes that require that)
- Loop between given points (just click begin and start point)
- Open CD's, wave files, mp3 files...

- Etc...

Artifacts (echoing effect) can be heard when slowing down, but I have the impression the creator still updates the product.

Here is the link to the programmers page with the (and I repeat myself) free download.

Have fun!

How to record your (electric) guitar

One of the main "swiss army knife" functions that your computer can accomplish is that of a recording device. Recording your own playing is the best way to find out how "well" or "not-so-well" you really play. You will be surprised (hehe). Every wrong note, every flaw in your timing will be exposed (to yourself only if you are to ashamed of the results...).

Keep in mind this article describes "a" solution to recording yourself and yourself alone (or in some cases just two people), it is not intended for those wanting to record a whole band!

Let's get on with it.

On the hardware side the most simple solution would be to buy a little adaptor at radio Radio Shack to be able to plug your "monstreous" 1/4-inch guitar cable jack into these tiny line- in inputs on your computer soundcard.

First of all: you need to use the line-in, never the mic in. Microphones deliver a very low output, so the signal is boosted tremendeously after the mic input. This results in a lot of hiss (that is amplified along with the signal) and distortion. Laptops mostly only feature a mic/ line in input.

Secondly: this solution is not giving satisfying results anyway. Nor the mic or line input on your pc is calibrated to handle the output of your electric guitar. The impedance mismatch will "strangle" the sound cutting out brilliancy and attack. Anyone having tried to amplify a guitar patching the cable directly into a mixing desks line in (live or in studio) will have observed the same.

One of the best solutions to record (both sonically and investment-wise) is to use a Guitarport, Toneport, Podxt or Podxtlive by line6.

All these devices are usb-soundcard solutions with EXTENSIVE amp and effects modeling capacities.

The Podxt and Podxtlive where primarly designed as modeling / effect units. The processing is done in the unit itself, so your computer has less work to do and live usage is very easy (your computer is not needed to use them).

The Guitarport and Toneport are designed as computer- audio interfaces (soundcards). The processing is done by your computer. They are great if you just need to record your guitar or want to study with your computer (with backing tracks or a backing track software...). They are not so handy for playing live since you then need you to carry along your computer.

All the tones (patches) of these can be saved to your computer and are interchangeable. That means that if you have the cash you could buy a Toneport for use with the computer. Design and save your sounds and dump them afterwoods into a PodxtLive for gigging and rehearsing.

I owned a Podxt for a while that I used primarly at home for practicing and recording. You can read a review I wrote here. I have since then traded the unit for a Toneport (you can read my review here). But why, you may ask.

Well I teach at different locations (4 schools) and began to carry along my laptop and Podxt as integrated backing track / playing/ teaching tool. The Toneport had 2 big advantages: 1. it is USB powered, one adaptor less to carry along in my backpack. 2. It is very light and that makes a difference too :-).

I do plan to buy a PodxtLive for gigging and rehearsing, but unfortunately some events in my "private life" made me run out of savings, so I will have to wait a bit for that to happen :-).

On side of the software you can start with the provided ableton live lite (included with the Toneport), but if you are new to computer- based recording this can be somewhat dounting. For starters I can recommend the freeware recording application Audacity. It is FREE and capable of multitrack recording, meaning you can import a wav or mp3 file and play it back recording your playing onto a new track alongside the imported or previously played track(s).

Altough it is not important in the context of using these devices for recording with Audacity, I should mention they come with so called "Asio drivers". Asio (Audio Stream Input Output) is a driver model developed by steinberg that allows for so called "low latency" operation, meaning that an audio signal delivered by a device to an application will need very little time to travel through the application before it's sent to the devices output.

As said before this is not important in this context, because the effected signal (amp emulation) is dealth with by the line6 hardware/ software combo. Asio drivers become important if you want to use (play) software synthesizers (in a sequencer for instance) or use the effects in a software package (like again a sequencer) in real time while playing.

Let's recapitulate:

Guitarport:

Guitar input only. Small and usb powered. Processing is done by the computer.

Toneport:

Guitar / Bass input and xlr Mic inputs (UX1: dynamic mics, UX2 with fantom power for condenser mic's). Guitar amp, bass amp, channel strip (console) modeling. Can use 1 mic and 1 instrument input at the same time, UX2: 2 mic's at the same time.

Podxt:

1 guitar input. Unit can operate standalone and as a USB recording device. Guitar modeling.

PodxtLive:

Same as Podxt, but integrated in pedalboard for convenient live use.

Note that major firmware and software updates are announced by line6. All units will share the same basic operating software and additional capabilities will be introduced for the different units.

It is also a good idea to check if your computer / chipset / usb chipset is capable of handling a usb soundcard and more precisely a line6 usb soundcard. Line6 has a neat help page with lots of info on the subject, recommended reading. You can also download and install a little utility that checks for compatibility at the same location.

I hope to post a little tutorial on using audacity and other recording software in the near future, stay tuned.

Introduction: About E-guitar

Hello and welcome to E-guitar.

Why E-guitar you may wonder. In the dark pre- internet and PC ages one had to attend schools or pay for private tuition and buy books (or go to a library) to learn or master something.

Things have changed considerably. At this time we have the internet at our disposal as a source of knowledge while the computer (be it a mac or windoze pc) has become a real "swiss army knife" capable of numerous tasks.

This blog is all about how the internet and your computer can help you in your development as a guitar player and musician. I will review (and let you review and ask your opinions on) recording equipment (soundcards, software ) suitable for guitarists, tab and sheetmusic resources, records, guitar Ebooks, guitar sites, forums etc...

Besides this blog I am also maintaining this guitar lessons site. Some posts may be summarised or introductory articles available there.

Have a nice stay at E-guitar.
