How To Pick The Best Synth For Bass: Buying Guides

Whether you plan to buy your first synth or simply wish to get a new model, it is always safe to see if the one you are looking for checks out everything on your list.

Some synths might have more features than what you need, while some might lack the ones you need, especially when connected with apps or software.

Here are a few important considerations you must keep in mind before you plan to buy one.

Look for a synth with a sequencer.

It’s quite likely that your keyboard usefulness is minimal to totally zero when you buy the first synthesizer.

In this scenario, you need to make confident that you have an optimized sequencer in the synth you want to buy.

It will basically allow you to write on the on-board memory a melody or bassline per note.

So you’re practically free to try tuning and resonance or to add some other effects when playing the template in the background.

Look for something small and compact.

There is no denying that huge synths seem cool! However, if you cannot access your synths easily, you might not be able to work around it.

Especially, if you are just starting out or have a limited studio space, opting for a compact and small-sized synth is a perfect decision.

You can easily give it a dedicated spot that you can access anytime rather than having to spend some time setting it up every time you need to use it.

Additionally, if you usually like to carry your own synth to jam sessions, it would make more sense to throw a smaller synth into your bag and get going.

Synths with powerful built-in speakers

If you are simply curious or a first-time synth buyer, there is a possibility that you don’t have a mixer, soundcard, or monitors.

These external devices help route your synth’s audio through. In the event that you do not have access to such external elements, then it would be useful for you to consider buying a synth with its own speaker.

Opting for an analog or a digital synth

If this your first synth purchasing spree, then you might already be confused and facing the eternal analog vs. digital argument. Everyone has their own opinion on this subject.

While some believe that analog synths sound warmer and authentic, some say that there isn’t any such specific difference in the sounds of the two.

However, what it comes down to is your preference and utility. If you are just starting out, then an analog synth would be great and more intuitive to learn on.

Remember to always buy from a reputable source.

Synthesizers are quite an investment. If you are looking for second hand or cheaper synths, you may be tempted to give away your cash.

However, being too hasty in such a situation may prove to be harmful to you. This is because whenever you purchase such items, you need to be sure of the quality and the terms.

So avoid buying second-hand synth machines. When you buy brand new ones, you don’t even have to worry about the quality nor the return policy.

So take your time, check out as many websites as you want, and always buy from a reputable source.

Only the technical aspects are not enough.

A synthesizer is essentially an instrument. So no matter how many functions, features, and sound quality it offers, you will not be comfortable using it unless you like the design and of the quirks it offers.

There is also quite a possibility that you might not like a synth after you have actually started using it.

It, therefore, is always safe to try and get a hands-on time before you make the actual purchase. If that is not possible, then read through the feedback and talk to previous owners.

You can also find various videos over the internet that show the working and the feedback on the pros and cons.

Make sure that you can learn and master it.

Many modern synthesizers are a lot less complicated. However, some are quite harder to master than others.

If you are new at this and want to buy your very first synth, then you must look for those models that are easy to learn and play without any stress and frustrating utilities.

On the other hand, if you are quite experienced or have hands-on experience with a couple of synths, then you should rather opt for those that give you the freedom to be creative and create your own compositions without any limitations.

It is, therefore, quite vital that you purchase a synth that has an interface that is comfortable to use and learn.

Choosing between monophonic vs. polyphonic sounds

Monophonic synths enable you to only play one note at a time. However, they are very ideal when it comes to the bass line as well as sequenced lines.

Such synths are perfect for adding an effect to your stage rig and can be added easily too.

And if you are using it in your studio, it will help you create a pure synthesis on the other hand polyphonic synth range between four voices to 128 voices in larger workstation units.

With Poly synths, you can work with rich pads and can also play two-handed for chordal accompaniment and complex harmony.

It is a bit larger than monophonic synths but there are also some very compact models.

MIDI implementation and Memory utility

If you are buying a synthesizer for the first time then you need to ask yourself questions like whether you wish to use the synth with your computer,

whether you wish to take notes so that you can record in real-time, whether you would like to store your composed and mixed synth sounds, etc.

If these functionalities are very important to you and you feel that they would play a vital role in your compositions, then you must ensure that the synth you are looking for has these functionalities.

Best Mono Synth For Bass: FAQ

What is an envelope follower?

This feature senses the input signal wavelength frequency range and dynamically adjusts tone.

Can I use a monophonic synthesizer like a polyphonic?

Modular analog synthesizers are monophonic, which is why only one note can be played at a current time. If you press more than one key, it will result in only one of the notes being played.

It is not possible to make a monophonic synthesizer play like a polyphonic. The sound of a modular synthesizer is larger in its monophonic form is therefore used best that way.

How many inputs does a vocoder need?

A vocoder usually takes two audio inputs. Input A for voice input and input B is usually a synth input from any external synth source.

Does a vocoder generate its own sound?

No, a vocoder does not generate its own sound internally. The input A analysis through a band of fixed filters that detect the energy levels in the input A at each of the filter frequency bands.

And then, the level envelopes are detected from these band-pass signals, which are then used to control input B.

Are there any limitations to the ACO chip?

The ACO chip follows an audio pitch between 25Hz to 6.4HZ and is quite larger than the frequency range of many instruments.

How are the chords played detected?

When you play a chord, it is automatically detected, and the name of the chord played is displayed on the front panel.

You can also choose from a list of chord detection in the setting panel like fingered 1, fingered 2, fingered 3 or Bass based on the utility of your synth.

Can I create a song over an empty song by overdubbing my performance?

No, ideally, you cannot. The sequencer can only be used to edit track in real-time and to playback songs.

Can I change the volume of a part of a recorded song?

You can change the content and elements of the songs after you start recording. So all you have to do is select the part that you wish to change and start overdubbing.

When you make the changes you desired, these are saved in real-time and are applied to the song.

Is it possible to change the name of a user song?

Many synths do not give you the option to change the name of a user song, while some do. So it depends on the utility and features provided to you.

When can the metronome go out of tune?

There is a possibility that the metronome might be out of tune or out of sync, especially when you fast-forward songs, rewind it, play demo songs, etc.

How can I record songs?

Mostly recording options are disabled unless a USB flash drive is inserted or it is connected to an external source. However, there are also some synths that give you the flexibility to record when in sequencer mode.

What kind of controls is possible on a device connected to the MIDI Out connector?

Generally, you can send note messages are other similar functionality but cannot control the tempo, synchronization, etc.

What exactly should the GATE Out polarity be set to? Positive or negative?

This highly depends on the model of analog synthesizer that is connected. Some synths support only negative polarity while some offer both a negative TRIG IN jack and a positive TRIG IN jack.

What is MIDI?

A MIDI is a data or you can say it is the standard for transmitting musical performance data. MIDI data basically contains instructions and information to enable sound to be produced by MIDI-compatible devices.

What is a hardware synthesizer?

Sound generation, using MIDI data to trigger Musical Notes are the most important hardware synthesizers.

Although some synths come in a keyboard shape, some are simply sound components on the monitor and don’t have a clavier.

You should, therefore, send data from your DAW or an external MIDI controller into the sound module.

What are MIDI messages or message notes?

You can categorize MIDI messages into channel and system messages.

The channeled message is a set of instructions such as note(s) for beginning and endnote, note speed, sound sort for playing the note, etc. device messages provide song-related information such as syncing, saving parameters, etc.
